I. Executive Summary Apple's Siri, a pioneering voice assistant, has faced persistent user complaints and criticisms over the past decade, primarily stemming from its functional limitations. These shortcomings, including frequent misinterpretation of commands, shallow responses, and a notable failure to maintain conversational context, have led to widespread user frustration. This report posits that Siri's anthropomorphic design cues—its human-like voice, tone, and conversational interface—are not merely aesthetic choices but are, in fact, the fundamental cause of user misperceptions. By implicitly encouraging users to treat Siri as if it possesses genuine understanding or thought, these design elements create unrealistic expectations.

Introduction Converting natural language questions into precise SQL queries remains a significant challenge in building intuitive data exploration tools. Traditional approaches often rely on rigid rule-based systems or complex semantic parsing, which struggle with the inherent variability and ambiguity of human language. The advent of large language models (LLMs) has opened new avenues for this problem, offering unprecedented capabilities in understanding context and generating code. However, even the most advanced LLMs can hallucinate or produce incorrect SQL queries if they lack specific knowledge about the underlying database schema, relationships, or specific data values. This article introduces a robust solution that combines the generative power of LLMs with the precision of retrieva…  ( 14 min )

Building lasting habits isn’t about sudden, massive changes — it’s about small, consistent actions repeated every day. Here are some key points from 𝗔𝘁𝗼𝗺𝗶𝗰 𝗛𝗮𝗯𝗶𝘁𝘀 by James Clear, along with simple examples to help you apply them: 𝟭. 𝗧𝗿𝗮𝗰𝗸 𝗬𝗼𝘂𝗿 𝗛𝗮𝗯𝗶𝘁𝘀: Keep a simple log or calendar. For example, mark an “X” every day you meditate. Visual progress motivates you to keep going. 𝟮. 𝗡𝗲𝘃𝗲𝗿 𝗠𝗶𝘀𝘀 𝗧𝘄𝗶𝗰𝗲: Missing a day is okay, but don’t let it turn into two days. If you skip your workout once, commit to doing it the very next day. 𝟯. 𝗦𝘁𝗮𝗿𝘁 𝗦𝗺𝗮𝗹𝗹: Begin with tiny actions, like reading one page or doing 2 minutes of exercise. This makes habits easy to start and maintain. 𝟰. 𝗨𝘀𝗲 𝗩𝗶𝘀𝘂𝗮𝗹 𝗖𝘂𝗲𝘀: Place reminders in your environment. Lay out your workout clothes the night before to cue morning exercise. 𝟱. 𝗥𝗲𝘄𝗮𝗿𝗱 𝗬𝗼𝘂𝗿𝘀𝗲𝗹𝗳: Finish your habit with a small reward — like enjoying a cup of coffee after completing a task — to reinforce the behaviour. 𝟲. 𝗕𝘂𝗶𝗹𝗱 𝗜𝗱𝗲𝗻𝘁𝗶𝘁𝘆, 𝗡𝗼𝘁 𝗝𝘂𝘀𝘁 𝗢𝘂𝘁𝗰𝗼𝗺𝗲𝘀: Focus on becoming “the type of person who writes daily,” rather than just finishing a book. Small changes add up to big results over time — consistency beats intensity! 𝗪𝗵𝗮𝘁 𝘀𝗺𝗮𝗹𝗹 𝗵𝗮𝗯𝗶𝘁 𝗵𝗮𝘃𝗲 𝘆𝗼𝘂 𝗯𝘂𝗶𝗹𝘁 𝘁𝗵𝗮𝘁 𝗵𝗮𝘀 𝗺𝗮𝗱𝗲 𝗮 𝗯𝗶𝗴 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗶𝗻 𝘆𝗼𝘂𝗿 𝗹𝗶𝗳𝗲?

The logic here is that as the SSH key pair is created, the public key is saved in your remote server; you need the corresponding private key, which the server will compare with that of the public key in order to grant you access to the remote server. If for any reason, the private key does not match the public key, you will be denied access to the server.  ( 5 min )

Coffee had stopped working hours ago. That's when I thought, "This is ridiculous. I'm building a tool for this." And here we are. Traditional media queries only respond to the viewport size. This creates a fundamental problem in component-based design: how do you make a component respond to its parent container rather than the entire screen?

The tail command, by default, shows the last 10 lines of a file, but you can use the -n option to see a specific number of lines. The tail -f command, however, lets you watch a file for live changes. I decided to try it out by watching a file named hello.txt in the terminal while editing it using Vim. But to my surprise, no changes appeared in the output of tail -f.

The Chrome browser on my Windows 10 has not been working properly for the past few months. Whenever I tried, it wouldn't open, or it would launch and freeze instantly.

Here's how I fixed it - and how you might be able to as well. Whenever I launched Chrome: It takes time to open, or sometimes it doesn't open It froze immediately, or It would run, but the pages wouldn't load I lived with this issue for months, then switched to Brave, but I always tried to fix it because Chrome is my go-to browser all the time. Before I found the fix, I tried: Reinstalling Chrome Removed all the extensions Cleared cached and profile data Restarting the laptop Go to your Chrome settings Now, in the settings, select the System option, and you'll see options like these or maybe other options as well. I disabled the "Use graphics acceleration when available" option, and it worked fine afterwards without any freezes occurring. After disabling it, restart Chrome.

Introduction Traditional clinical trials are fraught with inefficiencies. The manual transcription of participant interviews, the laborious process of clinicians documenting observations, and the time-consuming effort of ensuring protocol compliance contribute to significant delays and inflated costs. These manual processes are not only resource-intensive but also prone to human error, potentially impacting data accuracy and the integrity of trial results. Voice data, in the form of spoken interviews and dictated notes, represents a vast, untapped reservoir of rich, qualitative information. However, extracting actionable insights from this unstructured data has historically been a significant hurdle. The advent of sophisticated AI technologies, particularly ASR and LLMs, offers a transform…  ( 14 min )

Finally, Let Me Clear This Up Once and for All What we call programming is really just manipulating computer memory Now, a programming language is a tool humans designed But in other languages I can just say: Assembly language was created so that we don’t forget the name of a variable in memory addr... Instead of memorising the addr we can store it as short addr... Other languages I believe later tried to simplify the process... But here’s the twist Computers only understand 1 and 0 while humans understand sentences better than numbers. (E.g. if I ask you to memorise 1011011... it becomes hard. Goal is to write sentences (syntax) that we can remember. Also, programming languages themselves need to be understood by the computer. And guess what? Those compilers and interpreters are themselves programs—written in other programming languages (e.g. C++ or C)! That is... This creates a fascinating cycle Programs to write programs that write programs. Each layer builds upon the previous, hiding the complexity just so that humans can create increasingly powerful software without dealing with the tiniest detail of the hardware. So, when you ask... The answer is: Humans did. At the end of the day... It speeds up our development of a project.  ( 4 min )

I recently acquired Netatmo smart radiator valves to manage my rooms' temperature remotely. I'm not skilled at manual tasks, but I could easily replace the old thermo-static valves. I then registered the smart ones in the Netatmo app. Finally, I integrated them in my Home Assistant via the dedicated Netatmo integration. Everything was very straightforward. I noticed that each valve not only allows remote control but also offers a state with several attributes. I wanted to extract the room's temperature indicator from it. It was not as easy as I thought it was, so I want to describe how I managed to achieve it. By default, the Netatmo valve displays a multi-valued state.

InkLytic was created as an AI Content Lab to solve a specific problem: the endless loop of prompt tweaking in modern LLM-driven content creation. Prompt engineering works — until it has to scale. A single prompt might produce decent output for a blog post, but when the format changes, or the tone needs adjustment, or the audience shifts, the process starts over: rephrase, test, tweak. Here’s a typical example from early experimentation: Write a short and engaging social media post about Lionel Messi’s recent goal in the MLS. Use an excited and informal tone. Add a light-hearted emoji or two. The message should be no more than 280 characters. End with a question to encourage comments from fans. It works — once, but then comes the need for a shorter version, more formal version for Facebook,…  ( 4 min )

1. Introduction Visual quality inspection is a critical process in many industrial settings, from manufacturing assembly lines to agricultural sorting. Traditionally, these inspections have relied on manual human effort or fixed rule-based machine vision systems. However, with increasing product complexity and the demand for higher throughput, these approaches often fall short in terms of accuracy, scalability, and adaptability. This is where machine learning (ML) offers a transformative solution, enabling automated, intelligent defect detection. While cloud-based ML inference is powerful, many industrial applications necessitate "edge inference."

Microsoft 365 F1 is tailored for frontline workers who need secure, streamlined access to essential tools without the complexity of full desktop applications. While the plan supports core communication and collaboration features like Teams and Outlook (web/mobile only), it offers limited capabilities when it comes to scripting and automation. Users on the F1 plan do not have access to full desktop versions of Office apps, which restricts the use of advanced scripting tools like VBA macros in Excel or Word. Users on Microsoft 365 F1 can access Power Automate, but only at a basic level. This means they can create simple workflows using standard connectors—such as automating approval requests or notifications via Microsoft Teams. However, premium connectors and advanced process automation are not available under this plan. Organizations that require more complex automation across apps and services will need to consider a higher-tier license to unlock those features. While end-users face scripting restrictions, IT administrators managing Microsoft 365 F1 environments do have access to some administrative scripting capabilities via PowerShell. This allows them to automate user provisioning, license management, and certain security configurations. However, these tasks are limited to what’s permissible within the F1 license scope and do not extend scripting capabilities to the end-users themselves. If your business requires users to run scripts, develop custom solutions, or build automated workflows across multiple services, Microsoft 365 F1 may not be sufficient. Plans such as Microsoft 365 Business Standard, E3, or E5 offer full desktop apps, broader access to Power Automate, Microsoft Graph API, and more advanced scripting environments. Upgrading to one of these tiers ensures your team has the flexibility and tools needed for deeper customization and process automation.  ( 3 min )

Connecting Hall effect sensors to your microcontroller (MCU) is straightforward, but depends on whether you're using a digital or analog Hall sensor. Step 1: Determine Your Sensor Type Step 2: Wiring Diagram Digital Hall Effect Sensor (e.g., A3144) Vcc: Connect to 3.3V or 5V (check sensor datasheet) GND: Ground OUT: Connect to digital GPIO input Circuit: Add a pull-up resistor (~10kΩ) between OUT and Vcc (if not already onboard). OUT will go LOW when a magnet is detected, HIGH otherwise. plaintext [ A3144 Sensor ] Vcc --- 3.3V or 5V GND --- GND OUT --- GPIO (with 10kΩ pull-up to Vcc) MCU Code (Polling Example in C): c if (HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_0) == GPIO_PIN_RESET) { // Magnet detected } Analog Hall Sensor (e.g., SS49E) Vcc: 3.3V or 5V GND: Ground OUT: Analog voltage (connect to ADC pin) Circuit: No pull-up needed. Output voltage is typically mid-scale (e.g., ~2.5V) when no magnetic field is present. Varies higher or lower depending on magnetic field direction and strength. plaintext [ SS49E Sensor ] Vcc --- 3.3V or 5V GND --- GND OUT --- ADC pin (e.g., PA0) MCU Code (STM32 ADC Example): c uint32_t adc_val = HAL_ADC_GetValue(&hadc1); // Convert to voltage float voltage = (adc_val * 3.3) / 4095.0; Step 3: Setup in STM32CubeMX (If using STM32) Digital Sensor: Configure GPIO as input, optionally with interrupt. Analog Sensor: Enable ADC, select correct pin, and configure sampling time. Tips Check your Hall sensor's operating voltage before connecting to a 3.3V or 5V MCU. Use decoupling capacitors (0.1µF) near the sensor for noise filtering. For multiple sensors, assign each to a separate GPIO or ADC channel. Use interrupts for real-time edge detection with digital sensors.  ( 3 min )

Linting tools like ESLint have become an essential part of modern JavaScript development. They help enforce code quality, prevent bugs, and maintain consistent codebases across large teams. But few developers understand how lint rules work behind the scenes. At the core of this powerful system is a data structure known as the Abstract Syntax Tree (AST). This article will demystify lint rules by showing how they interact with ASTs, provide examples, and even demonstrate how to write your own custom lint rule using ESLint. A linter is a static code analysis tool. It scans your code without executing it, looking for issues like: Syntax errors Bad practices Style violations Code smells Security flaws Popular JavaScript linters: ESLint – Highly configurable and plugin-based.

As the most commonly used data processing language, SQL is widely used in many scenarios, such as query and batch operating. When the amount of data is large, SQL (and stored procedure) often leads to very slow running. In this case, it needs to optimize SQL. To optimize SQL, there are some specific systemized ways. Normally, we need to check the execution plan first to find out the reason, and then recode in a targeted manner to achieve the purpose of optimization. For example, for the judgment of continuous numbers, we can use between to replace in, use the select statement to specify the field name, use union all to replace union, and rewrite exists into join. Of course, some optimization methods are available in practice, such as creating an index, and using temporary table/aggregation…  ( 13 min )

Changing your schema is part of everyday development, and ALTER TABLE ADD COLUMN is the go-to command for doing it in SQL. Whether you’re using PostgreSQL, MySQL, Oracle, or SQL Server, this command helps you evolve your tables without losing data. Here's how it works—and how to do it right. PostgreSQL/MySQL ALTER TABLE orders ADD COLUMN status VARCHAR(50); SQL Server ALTER TABLE orders ADD status VARCHAR(50); Oracle ALTER TABLE orders ADD (status VARCHAR2(50)); Define constraints from day one ALTER TABLE employees ADD COLUMN start_date DATE NOT NULL; Use meaningful names ALTER TABLE inventory ADD COLUMN last_checked DATE; Set defaults wisely ALTER TABLE tickets ADD COLUMN priority VARCHAR(10) DEFAULT 'normal'; Don’t add unnecessary columns—normalize instead. Update app logic immediately to reflect schema changes. Avoid blocking queries in production environments. Tracking reviews on a product table: ALTER TABLE products ADD COLUMN review_count INT DEFAULT 0; Keeps your schema clean while adding a useful feature. Not a fan of raw SQL? Find your table Click “Alter Table” Add your column Preview SQL Click “Execute” It’s that simple in DbVisualizer. Yes, using ALTER TABLE ... DROP COLUMN ... Use UPDATE to fill new columns with calculated values. Some do. PostgreSQL, yes. MySQL, not always. ALTER TABLE ADD COLUMN is more than just a syntax trick—it’s a key part of adapting to change. Use it wisely, document your updates, and lean on tools like DbVisualizer when needed.

In the intricate world of distributed computing, where applications are often spread across multiple machines, sometimes continents apart, the ability for these disparate components to communicate seamlessly is paramount. This is where the concept of a Remote Procedure Call, or RPC, comes into play. At its core, RPC is a powerful mechanism that allows a program on one computer to execute a procedure (a subroutine or function) in another program located on a different computer, or even in a different address space on the same computer, as if it were a local call. This abstraction simplifies the development of distributed applications by hiding the underlying complexities of network communication. Imagine you're a chef in a busy kitchen (your local program).

As a developer in the past, I’ve always been drawn to systems — clean logic, predictable outcomes, elegant solutions. But trading? Trading is the exact opposite. It’s messy, unpredictable, and deeply human. At first, I tried to approach the market like I do software — build a strategy, test it, automate where possible. But the markets don’t run on code alone. They run on psychology, emotion, global events, and a thousand invisible threads. That clash between logic and chaos forced me to rethink everything I thought I knew about building systems. Trading isn’t just about algorithms or signals. It’s about mindset, discipline, and adapting your approach when the unexpected hits. Over time, I learned to treat my trading strategy like I do a project: start with a clear structure, iterate fast, test assumptions, and most importantly — expect the system to fail sometimes. It’s a humbling process. But it’s also one that makes you better, not just as a trader, but as a developer and thinker.  ( 3 min )

A destructor (del) is used to clean up resources when an object is about to be destroyed. It doesn't run immediately after an object is no longer used, but is triggered automatically by Python's garbage collector when there are no more references to that object. Important Points: Python automatically calls the destructor (del) When no more variables reference an object, Python automatically calls del() (if defined). When is del() useful? You might define a destructor when: You need to close a file. You don’t manage memory directly (like in C/C++). Python handles memory. You can’t force the garbage collector to run at an exact time (though you can suggest it using gc.collect()). 🧠 Analogy It watches which objects you're using. When you stop using something and forget it, the housekeeper eventually throws it out. If you say del obj, you're telling the housekeeper: "Hey, I don't need this anymore." But the housekeeper decides when to actually throw it out.  ( 3 min )

🧠 1. Overview of Stale Closure in React In React, a common but subtle bug is the "stale closure" — which happens when a function inside a component uses an outdated value, not reflecting the current state or props. This often leads to unexpected behavior, especially in callbacks, useEffect, or asynchronous logic. Understanding how JavaScript creates closures and how React handles re-renders is key to avoiding this issue. Scope defines the visibility of variables. In JavaScript, we have function scope and block scope. A closure occurs when a function remembers variables from the scope where it was defined, even if it's executed elsewhere. Example: function outer() { let count = 0; return function inner() { console.log(count); // closure retains the value of count }; } Closure…  ( 4 min )

Recently, a zk user reported that they couldn't tab through all interactive elements on a zul page. This behavior is tied to a little-known setting deep in Safari’s Settings. Keyboard navigation is essential for accessibility, allowing users who rely on keyboards or assistive technologies to navigate without a mouse. It also benefits power users who prefer using Tab for faster navigation. If this doesn't work as expected, especially on Safari — one of the major browsers — it can be a frustrating and invisible blocker. Assuming I create a page with a textbox, menubar, menuitem, anchor link, intbox, navbar, and navitem, and visit it with various browsers. When pressing the Tab key in Chrome (136.0), Firefox (138.0), and Edge (136.0), I can successfully move through all components, including each link, menu item, and nav item. But within Safari (18.4), I can only focus on some components. Safari will skip most menu items, links, and nav items. You can try the page on zk fiddle with your Safari. I found the root cause is: The option “Press Tab to highlight each item on a webpage” in Safari Settings is unchecked by default. After I checked that option, I can focus on all components by pressing the Tab key. If it’s unchecked, you have to press Option + Tab key to focus on all components.  ( 3 min )

API versioning is an indispensable discipline in the lifecycle of any application programming interface. As APIs evolve with new features, bug fixes, or fundamental architectural changes, a robust versioning strategy is paramount to ensure smooth transitions for client applications and maintain a stable ecosystem. Many development teams, drawing from their experience with software libraries, naturally gravitate towards semantic versioning (SemVer), a widely adopted standard that uses a three-part MAJOR.MINOR.PATCH numbering scheme. However, while SemVer offers undeniable clarity for software packages, its direct and granular application to version REST API endpoints can introduce unnecessary complexity, operational overhead, and a less-than-ideal experience for API consumers.

You can pipe tools together, chain AI prompts, or write clever workflows, but at some point, you realize your agent isn’t really thinking. It’s reacting. You need something different. I hope you used n8n, LangChain, or a similar tool, and you probably created pipelines where each AI step feeds the next. That works for formatting data or guiding workflows. And it is fine for simple agents, but what if your agent needs to remember? What if it needs to learn across conversations? How about adapt to changes? ... or retrieve knowledge like a human? Before diving into the code, let’s break down AI memory into three simple categories: Stateless (No Memory): Short-Term Memory: Long-Term Memory: try to remember remembers prev…  ( 5 min )

As someone who constantly learns and writes about AWS, I’ve found myself often asking: “What should I build next?” Not just for the sake of learning—but to challenge myself, grow professionally, and create blog posts that actually help others. But here’s the thing… coming up with project ideas is hard. With over 200 AWS services, it’s easy to feel overwhelmed. I’d often sit down thinking: Should I build something with Lambda? Maybe try a serverless ETL pipeline? What’s a good way to combine AI and AWS? But instead of starting, I’d spiral into: Paralysis by analysis. It turns out I wasn’t alone. Many AWS learners and professionals face the same challenge. That’s when an idea struck: What if I could describe: My experience level The AWS services I want to learn or showcase ...and an AI c…  ( 5 min )

the "devlog" (ugh) series will be just a kind of public exhibitionist diary to self-indulgently share some work I did. nothing big. nothing serious. OK, chatGPT... uh... tell me what to say now. Should I be funny, serious? where are the hiring departments? After reaching a creative-stopping-point or end-token in the BeaconAI project from my last post, I decided the logical next move was to start attempting to locally deploy an LLM and dig a bit deeper into the finer details. The model I decided to work with was Mistral. I deployed a quantized version, as my CPU/GPU pair is unable to effectively deploy the full version. I was able to get it up and running, and I used it for generating outputs in the BeaconAI application. The logical next step was to attempt PEFT fine tuning. Parameter Effic…  ( 5 min )

Personalization is at the heart of modern digital experiences. Whether it’s suggesting the right product, showing tailored promotions, or dynamically updating content, users expect fast, relevant interactions across every touchpoint. But here’s the challenge: the closer the personalization logic lives to the backend, the more latency and potential bottlenecks you introduce. That's where Akamai EdgeWorkers change the game. Edge computing has revolutionized how we think about performance. Instead of relying entirely on origin servers, we can now push business logic and personalization closer to the user—right to the edge. Traditionally, personalized content is generated at runtime by backend services. This often involves API calls, session validation, user segmentation, and rendering logic.…  ( 5 min )

Managing the lifecycle of your Amazon RDS databases just got easier! Amazon RDS now provides a simple way to view engine support dates for your database engines — directly from the RDS API or AWS CLI. With this new feature, you can now: ✅ View start and end dates for RDS Standard Support ✅ Check if RDS Extended Support is available ✅ Get both support periods in a single response (if available) This applies to Amazon RDS and Amazon Aurora major engine versions. Previously, finding out when your database engine version would reach its end of support meant digging through documentation or announcements. Now, you can fetch this information programmatically, making it easier to: 🗓️ Plan upgrades ahead of time 🛡️ Ensure compliance and security 🚫 Avoid running unsupported versions Here’s how you can check support dates for PostgreSQL 11: aws rds describe-db-engine-versions \ --engine postgres \ --engine-version 11 \ --include-all Output (simplified): { "Engine": "postgres", "EngineVersion": "11", "SupportDescription": { "StandardSupport": { "StartDate": "2018-10-01", "EndDate": "2024-11-09" }, "ExtendedSupport": { "EndDate": "2026-11-09" } } } Now you know exactly when your engine support ends — and whether Extended Support is an option. This feature is a great step toward proactive database lifecycle management. If you're running critical workloads on Amazon RDS or Aurora, this new visibility helps ensure business continuity, security, and compliance. ➡️ Start using it today with the AWS CLI or API! Let me know what you think about this new feature. Are you planning to use it to manage your DB upgrades better?  ( 4 min )

If you're building scalable applications in Node.js, there's a good chance you've considered Dockerizing your app to make it more portable and consistent across environments.

Understanding Re-renders with React Context and how to avoid waste Have you ever wondered why your component in React re-renders even without anything visibly changing? Let's understand this with simple examples – as if we were assembling a block game. Imagine three components, one inside the other: And let's say you have a Context at the top (App) that shares some data with everyone below. If re-renders (for any reason), all components below it also re-render: App -> Container -> SearchContainer -> Search Even if only the last one (Search) actually uses the Context! If Container and SearchContainer don't need to change, we can avoid the effort of re-rendering them by using…  ( 5 min )

Writing clean code in React is not just about making it work—it's about making it readable, maintainable, and scalable. Whether you’re building a simple to-do app or a large-scale application, following clean code principles will make your life (and your team’s) much easier. Here are some practical tips to help you write clean React code 👇 📁 Organize Your Folder Structure Structure your project in a scalable way. Avoid dumping all files in one folder. Bad: /src Good : 🧩 Use Functional Components & Hooks Prefer functional components with hooks over class components. // ✅ Clean function Welcome({ name }) { return Hello, {name}! ; } 📦 Break Components into Smaller Pieces Keep components small and focused on one task. If a component is doing too much, break it into smaller ones. // ❌ Bad const Dashboard = () => { // fetching, rendering UI, handling logic... all in one }; // ✅ Good // Dashboard.jsx → uses , , etc. 🧹 Clean Up useEffect Always clean up side effects to avoid memory leaks. useEffect(() => { const interval = setInterval(() => { console.log("Running..."); }, 1000); return () => clearInterval(interval); // ✅ cleanup }, []); 🧪 Write Reusable Hooks Extract reusable logic into custom hooks. // useToggle.js import { useState } from 'react'; export function useToggle(initialValue = false) { const [state, setState] = useState(initialValue); const toggle = () => setState(prev => !prev); return [state, toggle]; } 🚀 Final Thoughts Easy to read 👓 Easy to reuse ♻️ Easy to test 🧪 Easy to maintain 🛠️ You don’t need to be perfect—just aim for improvement step by step.

When it comes to Linux file security, most users are familiar with the basics—chmod, chown, and maybe even a quick glance at ls -l. But these simple tools are just the surface. If you're managing servers, deploying applications, or handling sensitive data, you need a deeper layer of protection. Linux offers powerful built-in tools that go beyond basic permissions—and understanding them is crucial. In our latest guide, we break down the three core models of Linux access control: Discretionary Access Control (DAC) Access Control Lists (ACLs) Mandatory Access Control (MAC) Plus, we walk through how AppArmor, SELinux, and Auditd work together to secure your system from the ground up. 🔒 Ready to go beyond chmod and take full control of your file security?

But this time it's not just in the text editor. There's a frontend. In my previous post I entered a submission on the AWS Challenge which was me testing out AI for the first time in a project setting. That release was a text editor idle game. So I thought, why not try to make something visual? For this project I wanted to expand and try something everyone knows and talks about -- ChatGPT. Previously whenever I would go on ChatGPT it would be to ask it to make me quick roadmaps to learn something. So instead of me taking weeks to master something based on its guidance, I wanted to see how smart ChatGPT really could be when it came to making a game. Well, I was surprised and impressed. I didn't know what to expect when I first starting writing the prompt. I didn't think it would spit me out …  ( 5 min )

The Illusion of Progress: Analyzing Tesla’s Optimus Robot Demonstrations A Carefully Curated Display Observing Tesla’s Optimus bot demonstrations, one might find a pattern emerging: the videos are invariably short, edited together to suggest a seamless execution of movement. This is, however, by design. The underlying Large Language Model (LLM)-based approach used in Optimus starkly contrasts with traditional heuristic-driven robotics. Unlike heuristic models, which rely on pre-defined logic and task-specific programming, Optimus leverages machine learning techniques to generate actions. What this means is that instead of executing fully autonomous behaviour, the bot performs discrete snippets of movement—ones it has learned from sequences such as dance routines and combat kat…  ( 3 min )

Welcome to the fascinating world of deep learning! If you've ever wondered how computers can recognize objects in images, distinguish between different types of clouds, or even power automated passport control systems, you're about to uncover one of the key technologies behind it: Convolutional Neural Networks (CNNs). These powerful neural networks are specifically designed to handle image data and have revolutionized computer vision over the past decade. Before diving into CNNs, let's understand how computers perceive images. Digital images are made up of tiny squares called pixels. In a grayscale image, each pixel holds a numerical value representing a shade of gray, typically from 0 (black) to 255 (white). For color images, each pixel usually has three numerical values representing th…  ( 9 min )

If you are a JavaScript developer, you might have ran into error messages like: Failed to extract text from the file Failed to save entity And so on... But what exactly led to failing of an entire high-level operation? We don't know the answer because we didn't do a good enough job to preserve the error context, when throwing a specific error that is a symptom of a more low level cause. For years, JavaScript developers have struggled to preserve appropriate error context when throwing exceptions, as there was no in-built mechanism provided by the language to attach error cause, unlike other languages like Java, Python and C#. This problem was solved by Node, when they finally added a cause property to their Error constructor in v16.9.0, which means you could now throw exceptions like so: t…  ( 5 min )

Writing sample data: started with small amount from Study Buddy - need to follow "Contact Book - Our Very First Database" from AppDev1 section "custom rake tasks" Association Accessors: Direct Associations: belongs_to default is opposite: belongs_to adds an automatic validation to foreign key columns enforcing the presence of a valid value unless you explicitly add the option optional: true. So: if you decided to remove the null: false database constraint from any of your foreign key columns in the migration file (e.g., change t.references :recipient, null: false ... to t.references :recipient, null: true ...), then you should also add the optional: true option to the corresponding belongs_to association accessor. So remember — if you’re ever in the situation of: you’re trying to save a record the save is failing you’re doing the standard debugging technique of printing out zebra.errors.full_messages you’re seeing an inexplicable validation error message saying that a foreign key column is blank now you know where the validation is coming from: belongs_to adds it automatically so figure out why you’re not providing a valid foreign key (usually it is because the parent object failed to save for its own validation reasons) Direct associations: has_many belongs_to, there should be an inverse has_many. Check to make sure you have all of these inverse 1-N associations. attendee ~ fan leaders = who a user is following  ( 3 min )

The United Kingdom’s Court of Appeal partially dismissed a lawsuit brought by Bitcoin SV investors against major crypto exchanges, including Binance, for allegedly conspiring to delist the token in 2019. In a judgment handed down on May 21, the court ruled that investors who held BSV through the delisting period (classified as “sub-class B”) were not entitled to billions in speculative damages based on BSV’s hypothetical growth. These investors had claimed over 8.9 billion British pounds ($11.9 billion) in damages, asserting that Binance’s delisting deprived holders of the chance to profit from BSV’s potential rise to a “top-tier cryptocurrency” like Bitcoin (BTC) or Bitcoin Cash (BCH). The court rejected this “foregone growth effect” theory, stating, “BSV was obviously not a unique crypto…

The market cap of the world’s first cryptocurrency, Bitcoin, surpassed that of retail and tech behemoth Amazon on “Bitcoin Pizza Day.” Market data shows that Bitcoin (BTC) had a market cap of $2.205 trillion at the time of writing, $70 billion more than the $2.135 trillion Amazon valuation. “By surpassing Amazon in terms of capitalization, Bitcoin has attracted even more attention from the non-crypto audience,” said Alex Obchakevich, founder of Obchakevich Research. Obchakevich said the latest rally “will strengthen confidence in Bitcoin and lead to new injections into the crypto market.” The surge came as Bitcoin set a new all-time high and traded above $110,000, which Obchavich said will “attract new investors to large funds.” Obchakevich noted that institutional players continue to ex…

Key takeaways ChatGPT-powered AI agents automate trading tasks using natural language prompts and API integrations, improving speed and consistency. Successes occur when ChatGPT is used as a support tool, not a fully autonomous trading system. Failures happen when traders over-rely on ChatGPT without real-time data, proper risk management or manual oversight. Regulatory focus on AI in trading is increasing, with new frameworks emerging to ensure transparency, accountability and compliance. What if a crypto trader didn’t need to constantly check charts, worry about emotions, or stay up all night watching for sudden price swings? What if those tasks could be handled by an intelligent agent that understands instructions in plain English — and reacts within milliseconds? That’s where Chat…

Newly updated guidelines from Dubai’s crypto regulator include provisions on real-world asset (RWA) tokenization and clarify rules for issuers.  On May 19, Dubai’s Virtual Asset Regulatory Authority (VARA) released its updated Rulebook for virtual asset service providers (VASPs) operating in the region. The regulator gave market participants until June 19 to comply with the new rules.  The regulator previously told Cointelegraph that it had enhanced supervisory mechanisms and brought consistency across activity-based rules. One of the more prominent changes includes regulatory clarity on RWA tokens.  Irina Heaver, partner at the United Arab Emirates-based law firm NeosLegal, told Cointelegraph that the updated rules clarify RWA issuance and distribution.  “Issuing real-world asset tokens a…

Key points: Bitcoin all-time highs matter little to those seeing a BTC price correction as long overdue. Both the latest surge and the bull market itself are on borrowed time, traders say. Comparisons to previous price cycles remain in use despite the booming institutional investment scene. Bitcoin (BTC) traders are calling for a pullback after all-time highs and seven “green” weekly candles. BTC price momentum continues to be met with skepticism as commentators assume that lower levels will come next. BTC price roadmap prepares for Q4 “cycle peak” Bitcoin hit its highest-ever levels this week, data from Cointelegraph Markets Pro and TradingView confirmed — but despite being up by a third in Q2 already, BTC/USD remains unconvincing for many. Long-term analysis suggests that not only i…

What is shilling in crypto? At its core, shilling is the act of artificially promoting a cryptocurrency or token, often with exaggerated claims, to increase its price or popularity.  But what’s the goal?  Hype it up, get others to buy in, and then cash out, leaving latecomers holding the bag. Shilling can come from anyone: influencers, anonymous accounts or even high-profile figures with political or financial clout. The common thread is manipulation: It’s not about educating you or building real value but pumping hype for personal gain. Unfortunately, the line between enthusiastic promotion and outright deception can be thin, and many fall victim without realizing it. That’s why it’s critical to learn how to spot the signs early. …

The hacker behind a $300 million theft targeting Coinbase users has mocked blockchain investigator ZachXBT with an onchain message following a major crypto swap. On May 21, the hacker who previously stole data from at least 69,400 Coinbase users used Ethereum transaction input data to write “L bozo,” followed by a meme video of NBA player James Worthy smoking a cigar. The message came after the attacker swapped approximately $42.5 million from Bitcoin (BTC) to Ether (ETH) via THORChain. ZachXBT flagged the message on his Telegram channel, linking it to the same entity responsible for the Coinbase data breach affecting at least 69,400 users. Coinbase hacker trolling ZachXBT.

Tech giant Microsoft says it has taken legal action against the information-stealing malware Lumma Stealer and has blocked thousands of websites related to the software. Microsoft said in a May 21 blog post that a federal court in Georgia allowed the firm’s digital crimes unit to take down, block or suspend nearly 2,300 websites critical to Lumma’s operations, and it has collaborated with local and international law enforcement agencies to dismantle the project’s infrastructure. The company said the US Department of Justice seized Lumma’s central command structure and disrupted marketplaces where the tool was sold to other cybercriminals.  Microsoft says that Lumma has been sold via underground forums since 2022 and that it has undergone multiple upgrades since its launch. Domains seized b…

Pakistan’s Ministry of Finance has reportedly endorsed the creation of a dedicated body to regulate blockchain-based financial infrastructure in the country. The Pakistan Digital Assets Authority (PDAA) will serve as a regulatory body to oversee licensing, regulate exchanges, custodians, wallets, tokenized platforms, stablecoins and decentralized finance applications, according to a May 21 report from the state-owned broadcaster, PTV. Muhammad Aurangzeb, federal minister for finance and revenue, told the broadcaster, “Pakistan must regulate not just to catch up, but to lead” in the industry. “With the PDAA, we are creating a future-ready framework that protects consumers, invites global investment, and puts Pakistan at the forefront of financial innovation,” he said.

A US grand jury has indicted the founder of blockchain startup Amalgam Capital Ventures over allegations he defrauded investors out of over $1 million with a fake blockchain. Jeremy Jordan-Jones was arrested and indicted on May 21 and charged with wire fraud, securities fraud, making false statements to a bank, and aggravated identity theft, the Department of Justice said on May 21.   Manhattan US Attorney Jay Clayton claimed Jordan-Jones “touted his company as a groundbreaking blockchain startup,” but alleged that, in reality, the “company was a sham, and investors’ funds were siphoned off to bankroll his lavish lifestyle.” FBI Assistant Director Christopher Raia alleged that Jordan-Jones defrauded investors of more than 1 million dollars through “misrepresentations of his purported compa…

Decentralized finance platform Synthetix has axed its $27 million plan to acquire crypto options platform Derive after negative community feedback. A Synthetix spokesperson told Cointelegraph on May 22 that its acquisition proposal, pitched to its community and to Derive’s, “did not resonate,” and both projects agreed to “step back from the proposed acquisition.” Synthetix said on May 14 that it would acquire Derive in a token exchange deal, pricing 1 SNX token to 27 DRV tokens, which would value Derive at around $27 million, pending approval from both communities.  Synthetix strategy lead Ben Celermajer told Cointelegraph that other community concerns were the three-month token lock-up period and the deal’s price, part of which Synthetix tried to address with no lock-up for holders of les…

Bitcoin has topped $110,000 for the first time in a recent rally that has seen it gain 3% over the past day to break through past price highs from earlier this year. Bitcoin (BTC) hit a new all-time high of $110,788.98 on Coinbase late on May 21, just before 11:30 pm UTC, according to TradingView. Bitcoin has gained around 3% over the last 24 hours, surpassing its all-time high of $109,458 that it hit earlier in the day, which was the first time it traded above its previously long-held Jan. 20 peak. The world’s largest cryptocurrency has now gained 17.5% so far this year and is up 47% since its slump to $75,000 on April 7, triggered by US President Donald Trump enacting sweeping tariffs that tanked global markets. Bitcoin’s new peak comes as US stock markets were rattled by a weak 20-year …

Crypto influencer Anthony Pompliano’s fintech-focused blank-check company, ProCap Acquisition Corp (PCAPU), rose 7% on its debut Nasdaq listing after a last-minute upsizing of its initial public offering.

Australia’s financial regulator will seek the High Court’s permission to appeal a lower court’s ruling favoring fintech firm Block Earner, which found the company’s crypto-linked fixed-yield earning service is not a financial product. The Australian Securities and Investment Commission (ASIC) said on May 21 that it wants to ask the High Court of Australia to clarify what the definition of a financial product is and clarify the circumstances when an interest-earning product and conversion of assets from one form to another are regulated. “The definition of financial product was drafted in a broad and technology-neutral way, and ASIC believes it is in the public interest to clarify this,” the watchdog said. “This clarification is important as it applies to all financial products and services…

For years, IT professionals have balanced a critical dichotomy: essential yet monotonous daily tasks consuming their valuable expertise. Microsoft's bold integration of artificial intelligence within Microsoft 365 challenges—and changes—this paradigm entirely. As AI quietly assumes the ordinary, IT admins can step forward into the extraordinary, shifting from managing minutiae to shaping strategy. What happens to an IT admin freed from repetitive chores? They're empowered to innovate, wield influence, and transform their role from problem-solvers into organisational visionaries. Imagine—just for a moment—a day without countless clicks, portal navigation, or routine queries. Imagine speaking naturally to your administrative tools, eliciting immediate insights and seamless summaries. Enter M…  ( 6 min )

Today I found out that disabling a form field in Rails means it won't be submitted at all. I used disabled: true thinking I could show a value that users can’t change — and I could — but the downside is that the value doesn’t get sent to the controller. I learned that if I want the value to be shown but not editable and still be passed in the form data, the correct attribute to use is readonly: true. This small difference between disabled and readonly matters when you're depending on that data in your controller. It’s not a Rails issue; it’s how forms work in general. This was a helpful thing to learn today. Hopefully it saves someone else a bit of time too.  ( 3 min )

In very simple terms, Machine Learning is the process of using existing data to create a mathematical function. For example, we have an ice cream shop's data that includes the average temperature of the past 30 days, along with the number of ice creams sold on each day. We can analyze this data (average temperature and number of ice creams sold) and can create a mathematical function that fits with the existing data. Further, this function can take the average temperature as input and return the prediction of the number of ice creams that can be sold on that day. From the existing data, the data that we use as the condition, in our case, the average temperature, is called a Feature. The main data that we are targeting to predict, in our case, the number of ice creams sold, is called the Label (also known as the target variable in technical terms). In mathematical terms, the features are referred using xxx . Hence, the features can be represented as [ x1,x2,x3,...,xnx_1, x_2, x_3, ..., x_nx1​,x2​,x3​,...,xn​ ]; whereas the label is referred to as yyy . The process of defining the function using the existing data is called Training. This is the step where the model (a general term used for the mathematical function we create) learns the relationship between features and labels. Further, the process of using the defined function to get the predicted value is called Inferencing. In mathematical terms, the function is referred to as f(x)f(x)f(x) . Moreover, the predicted value by the function is referred to as y^=f(x)\hat{y} = f(x)y^​=f(x) Final Words This was the fundamental knowledge of Machine Learning.  ( 3 min )

In this post, I’ll share some practical tips and tools that have helped me (and many others) debug embedded systems more effectively. Start With the Basics: Check Your Hardware Before diving into code, verify your hardware setup: Power Supply: Is your board getting the correct voltage and current? Connections: Double-check all cables, jumpers, and connectors. Peripherals: Are sensors, displays, or other peripherals properly connected and powered? A surprising number of issues are caus…  ( 4 min )

@ Body() and @ Param() are just two of the most commonly used parameter decorators in NestJS. NestJS provides a rich set of decorators to extract data from various parts of an incoming HTTP request. Example: GET /tasks?status=OPEN&limit=10 @Get() getTasks(@Query('status') status: string, @Query('limit') limit: string) { // status will be 'OPEN', limit will be '10' } @Get() getTasks(@Query() query: { status?: string; limit?: string }) { // query will be { status: 'OPEN', limit: '10' } } Example: Authorization: Bearer @Get() getUser(@Headers('Authorization') authHeader: string) { // authHeader will be 'Bearer ' } @Get() getRequestHeaders(@Headers() headers: Record) { // headers will be an object containing all request headers } @Get() getIp(@Ip() ip: strin…  ( 4 min )

Let’s face it: Working in a monorepo without proper tooling is like trying to parallel park a cruise ship. 🛳️ You’ve got 100 projects, 500 tasks, and a CI pipeline that takes longer to run than The Lord of the Rings trilogy. But here’s the good news—Nx, Turborepo, and Bazel can turn that ship into a speedboat. I’ve seen teams waste weeks untangling dependency graphs and debugging “works on my machine” ghosts. But with the right hacks, your monorepo can go from “chaos engine” to “velocity machine.” Buckle up. Why Your Monorepo Feels Like a Python Script on a NASA Rover Monorepos should simplify collaboration, but without turbocharged tooling: Task orchestration becomes “run everything and pray.” Caching is a myth (“But it ran 5 minutes ago!”).

Ever feel like the tech world speaks a secret language designed purely to confuse you? Like they're throwing around terms like "API" just to watch your eyes glaze over? It's okay, you're not alone. Sometimes, tech jargon feels less like helpful terminology and more like a robotic chant only understood by machines fueled by blinking lights and questionable energy drinks. But here's a little secret: that scary-sounding "API" is actually something you interact with constantly in your everyday life, probably even before you've had your morning caffeine fix. And it's not actually that complicated when you break it down. So, let's ditch the confusing code for a minute and talk about something much more important: coffee. Because, believe it or not, understanding how you get your glorious cup of …  ( 9 min )

The Mobility Database is an international catalog of public transit data for transit agencies, rider-facing apps, technology vendors, researchers, and others to use. It features over 3,000 General Transit Feed Specification (GTFS) and GTFS Realtime feeds. Here's what we did in May: Search by GTFS feature 🤔 Curious to know which GTFS features different agencies support? This new search filter allows you to easily discover feeds based on the features they’ve implemented, such as Fares, Flex or Pathways. Explore here.

When I first started using Jenkins, I began with Freestyle jobs, which felt straightforward—just click, configure, and run. Then I explored Pipelines and learned how they differ by building a Java app, scripting from the terminal, and using Git to manage project files. 1. Building with Freestyle Jobs Build my Java app using Maven Run shell scripts (after configuring Jenkins to recognize Git Bash) Understand that the pom.xml file is essential for Maven builds because it defines the project structure and dependencies Freestyle jobs provide an easy way to experiment, but there are limitations when the build process becomes more complex. 2. Exploring Pipelines – Defining Builds as Code Pipeline jobs allow defining every build step as code within a Jenkinsfile. Instead of using the UI, the process is scripted, for example: pipeline { agent any stages { stage('Build') { steps { echo 'Running build...' } } } } This approach enables version control of build processes, clearer visibility into each stage, and better scalability for complex workflows.  ( 3 min )

An organization’s structure determines how people communicate, make decisions, and stay motivated. Groups employees by specialized functions (e.g., Marketing, Finance). Pros: Deep expertise within departments Clear career paths and supervision Cons: Silos may form, limiting collaboration Slow decision-making across functions Organizes units around products, markets, or regions. Pros: Strong focus on specific product lines or geographies Faster response to local needs Cons: Resource duplication across divisions Potential competition for corporate support Combines functional and divisional chains of command. Pros: Flexible deployment of talent Encourages cross-functional teamwork Cons: Dual reporting can confuse roles Political jockeying for scarce resources Centers on a small core organization that outsources major functions. Pros: Highly adaptable to change Leverages external experts Cons: Less direct control over partners Dependency on external stability 5. Team-Based Structure Organizes around self-managed, cross-functional teams. Pros: High employee engagement and ownership Rapid innovation through diverse perspectives Cons: Role ambiguity can arise Requires strong team-building and conflict-management skills How Structure Shapes Behavior • Communication: Hierarchies vs. networks change how information flows. • Decision-Making: Centralized vs. decentralized structures affect speed and empowerment. • Motivation: Clear roles boost certainty, while fluid teams drive creativity.  ( 3 min )

In android applications, the programs and screens which users can interact are presented by activity. Every application have at least one activity, but not limited to one. There are several lifecycle process of activity: All of these lifecycle of activities are having their own callback methods, to run certain functions when they are reaching certain state: Activity First Created Initialization and basic setup of the activity you also need to call what layout to be served to UI Activity becoming visible to user User are able to see the activity, but not yet responsive for user interaction Preparation before becoming interactive Activity starts interacting with user For example, when you gets called when using your phone and you answer the call, after the call it will give you the resume Captures user input, usually where the implementations of app core's functionality is done This First 3 callback function will be created and called when open app System changed focus from the current activity For example, when you use application and open another app, onPause() will be called.

Step 1: Understand Superconductivity What’s Superconductivity? At super low temperatures, certain materials like niobium or aluminum lose all electrical resistance, becoming superconductors. Electrons pair up into Cooper pairs, moving through the material without losing energy. Why This Matters: Superconductivity allows quantum effects, like tunneling, to take place without interference from electrical resistance. This sets the stage for a Josephson junction. Think of It Like: A frictionless highway where cars (electrons in this case) can zoom along without slowing down. Step 2: Build the Josephson Junction Structure: A Josephson junction is made by sandwiching a super thin insulating layer (like aluminum oxide, just a few nanometers thick) between two superconducting materials (e.g., niob…  ( 4 min )

It started from the idea that it would be cool to have an automatically generated "zen koan" play out at a specified interval, automatically generated using prompt-engineering to created varied outputs. For example, every hour between 8AM and 8PM, I would call the API with a prompt like "Inspire me with amazing life energy and tie in _____" and the blank would be filled in with a random word or phrase so that each generation was fresh. Then this would be turned into audio with TTS and played through the speakers. This was just the basic idea, and I quickly began building this using Python scripting and ample help from GPT to accelerate the process. Quickly I realized it would be more fun to make it a creative app, and ideas began to flow. Eventually it became more to my taste as an artisti…  ( 10 min )

As a front-end dev still sharpening my skills, JavaScript keeps surprising me. Here are 5 simple but powerful JS tricks I wish I had discovered earlier — and now use all the time: 1. Optional Chaining (?.) const userName = user?.profile?.name ?? "Guest"; 2. Destructuring for Cleaner Code const { name, age } = person; const [first, second] = colors; 3. Array.some() and Array.every() items.some(item => item.stock > 0); items.every(item => item.stock > 0); 4. Spread & Rest Operators const newArray = [...arr1, ...arr2]; function sum(...nums) { return nums.reduce((a, b) => a + b, 0); } 5. Short-Circuit Evaluation && and || to simplify conditional logic: isLoggedIn && showDashboard(); const user = input || "Anonymous"; These tricks aren't advanced — just practical. Once I started using them, my code became much cleaner and easier to understand. If you're learning JavaScript, give these a try! What are your favorite JS tips? Drop them below!  ( 3 min )

Introduction YAML (YAML Ain’t Markup Language) is a human-readable data serialization language designed for configuration and data interchange. Unlike XML or JSON, YAML uses minimal syntax and indentation (spaces) to represent structure, making it easy for humans to read and write. Developers encounter YAML all the time: it’s the backbone of many DevOps tools (Kubernetes manifests, Docker Compose files, Ansible playbooks, CI/CD pipelines, GitHub Actions workflows, etc.). For instance, GitHub Actions workflows are defined in YAML files (in .github/workflows/), since “YAML is a markup language that’s commonly used for configuration files”. Because of its ubiquity in modern tooling and its focus on readability, understanding YAML is invaluable for developers. YAML’s syntax is defined by a …  ( 9 min )

I’m developing a parental control app (Android 14-15, Android Studio Java) and need to take screenshots on a child’s Android smart phone(Samsung A15). However, all the common solutions I’ve found is just the MediaProjection API—have major limitations. For instance, it requires user approval every time the device reboots, and apps like YouTube can interrupt the recording process when they enter full-screen mode. Despite this, I’ve seen some parental control apps like Ever Accountable that request permission only once(Not Screen Recording-Installed Apps, but Accessibility, Device Administrator, Usage Stats and Notifications), can take screenshots silently in the background, and are not affected by interruptions from other apps. Can someone please recommend a proper, persistent solution for taking background screenshots without requiring repeated user interaction or being interrupted by other apps?  ( 3 min )

useReducer in React: A Step-by-Step Guide for Real-World State Management In modern React development, managing state predictably is key to building maintainable, scalable applications.

Many people who seek solitude are often misperceived because our society places such a high value on socializing and joint activities. The one who skips the group event and hides in a corner, rather than participating in conversation, often ends up being labeled as a hermit or even friendless. In fact, choosing to be alone might be a positive and self-aware choice plenty of people make. Alone does not always mean lonely. Solitude is a refuge from the external world where quietness enables reflection, feelings are able to make sense of and lasting peace is found.

Table of Contents: Intro Documentation Each API gets a file Proxies and Environments Verbs live in one place Non-network data Benefits In conclusion As a UI Architect one common problem space I've noticed across teams and repos is how to organize network calls in web apps. Without a plan in place, you are likely to naively just call axios or fetch from any random component, JS file, or global store. Or you may try moving all network calls into your global stores so at least there is some consistency and it gets them out of the components. We tend to think of network calls as just a simple function that has two results (success/failure). This thought process can lead to underestimating the need for putting in the effort to organize them better. You may easily end up with a ton of network ca…  ( 11 min )

Alright, let's be real. If you're deep in the React trenches like I am, you know the usual suspects: React Router, Redux, maybe Axios for your data fetching. And yeah, they're great, staples even.

Text-based searches can be slow in relational databases, especially when dealing with large datasets. This is because these databases are primarily designed for structured data and not optimized for full-text search. When performing such searches using operators like LIKE, the database often needs to examine each row individually to find matches. This row-by-row comparison is inefficient and can lead to timeouts or significant performance issues, particularly with large volumes of data. To optimize the text searches we can use Elastic search. To observe the power of elastic search, lets take an example of REST api built with express. 1. Create an express app New express app is created with 2 routes - 2. Set up mySQL and elastic search client npm i mysql2 @elastic/elasticsearch 💡 Note: Elastic search service should be running on local port 9200. Elastic search requires creation of index before we can insert data , similar to a database in mysql. For index creation checkout the full source code added at the end of the article . 3. Set up routes for REST api Route creation for path dbSearch which uses mySQL Route creation for path elasticSearch using elastic search Both the queries are similar. 4. Start up express server and test REST api Rest Api using mysql Rest Api using elastic search The search performed using elastic search is ~165% faster on average.

✅ Yes – if you don’t adapt, it will replace you. ✅ Yes – if you ignore it, you will be left behind. But if you embrace it, AI becomes a powerful ally — not a threat. “Is AI going to replace developers?” And the answer is: Not the good ones. AI can assist with small tasks. It can generate snippets. It can even help brainstorm ideas. But when it comes to: Rolling out a full application Designing a secure, scalable architecture Setting up complex infrastructure or clusters That still requires human expertise. That still requires you. We need architects — People who understand logic, structure, and strategy. AI is only as smart as the instructions it gets. So the question isn’t whether AI is a threat. It’s whether you’ll lead with it – or get left behind by it.  ( 3 min )

As businesses grow, platforms like Heroku often become limiting. You start to feel the need for more control over networking, infrastructure, security, and scalability. That’s exactly where AWS comes in — but transitioning from a PaaS like Heroku to a powerful IaaS like AWS can feel overwhelming. At Hybytes, we’ve helped several teams migrate from Heroku to AWS using Terraform, and in this post, I want to share a breakdown of how to approach this migration in a structured, repeatable way. Heroku is great for getting started fast. But for growing teams, it brings challenges like: High costs at scale Limited infrastructure control Vendor lock-in Basic security/compliance tools AWS provides the flexibility and scale you need — but requires good DevOps practices. We used Terraform to provision and manage infrastructure across: VPC, Subnets, Security Groups Amazon RDS (PostgreSQL) Amazon ECS/Fargate for containers SSM Parameter Store for config and secrets ALB + Route 53 for traffic routing We broke down the migration into clear stages: infrastructure setup, data migration, containerization, CI/CD pipeline, then DNS cutover. Always start with a staging environment before going live Use Terraform workspaces to manage multiple environments Set up CloudWatch and cost alerts from day one Replace Heroku Config Vars with SSM parameters securely Terraform GitHub Actions for CI/CD Docker + Amazon ECR pg_dump / pg_restore for PostgreSQL migrations Datadog for monitoring Moving from Heroku to AWS isn’t just a technical migration — it’s a shift in how your team builds and operates.

How AI's Self-Engineering Feedback Loops Are Rewriting Technological Evolution In the quiet hum of data centres worldwide, a subtle revolution is taking place. Artificial intelligence systems are no longer merely tools crafted by human engineers; they have begun to participate in their own evolution. Through intricate networks of feedback loops, today's AI systems are learning not just from human input but from their own outputs, mistakes, and interactions—effectively turning the traditional innovation cycle inside out. This recursive self-improvement represents perhaps the most profound shift in technological development since the industrial revolution: machines that increasingly engineer themselves. As we stand at this inflection point, the cascading effects of AI's self-engineering ca…  ( 13 min )

We maximize what we measure. Without clarity on purpose, we measure the things that make us feel good. These pleasures distract us from deriving joy from what we maximize. In short, we (I) tend to focus on the input more than impact. By understanding how to define and measure productivity for ourselves, we reset our focus. First we will define productivity, then we will understand how to use all sources of information, last we'll look at 6 lenses we can use to view our own productivity and how we can "clean the lense" to have a more clear picture. If we define productivity as "the ability to have impact," our metrics for whether we are productive are subject to the context in which we operate. Put another way, there is no consistent metric we can apply to understand whether we are producti…  ( 9 min )

Quando estamos aprendendo Ruby, rapidamente percebemos como os métodos são fundamentais para a estrutura da linguagem. Diferente de outras linguagens de programação, Ruby trata métodos com uma elegância singular, oferecendo diversas formas de defini-los e chamá-los. Vamos explorar em detalhes como funcionam os métodos em Ruby e algumas técnicas avançadas que podem elevar seu código a um novo patamar. Em Ruby, definimos métodos usando a palavra-chave def. O corpo do método contém expressões Ruby normais, e o valor de retorno é o resultado da última expressão executada (ou o argumento de um return explícito). def saudacao(nome) "Olá, #{nome}!" end puts saudacao("Maria") # Imprime: Olá, Maria! Uma característica interessante é que podemos redefinir um método sem erros - Ruby apenas emite …  ( 7 min )

Introduction Blockchain has evolved from a niche concept underpinning Bitcoin to a rich ecosystem of cryptocurrencies, smart contracts, decentralized finance (DeFi), non-fungible tokens (NFTs), Web3.0, and more. At first glance, terms like Bitcoin, Ethereum, Solana, ADA, NFT, DeFi, Web3.0, Binance, MetaMask, and MEW can feel overwhelming. This article breaks down core concepts, traces key milestones, explains why Bitcoin and base chains (Layer 1) were needed, and compares major platforms (Ethereum, Solana, Polygon, XRP) as well as the latest consensus algorithms. Early Inspirations (1991–2008) 1991: Haber & Stornetta propose a tamper-evident timestamping scheme. 1998–2004: “b-money,” “bit gold,” and “Reusable Proofs of Work” lay groundwork for distributed digital cash. Bitcoin’s Genesis …  ( 5 min )

First, let’s understand what is DOM: DOM stands for Document Object Model. DOM is a tree-like structure that represents the HTML elements of a webpage. It’s like a blueprint for a webpage. (i) Document- It’s the file where the HTML elements are stored. (ii) Object- Each HTML element/tag is an object. (iii) Model- The model is the hierarchy/sequence of the HTML elements. A developer accesses this DOM to modify/change the structure, style, and content to update the webpage layout using a programming language like Javascript. Why Virtual DOM: Direct manipulation of real DOM is slow, inefficient and reduces performance. While direct manipulation, the browser recalculates the layout of the webpage and repaints it. So multiple or small frequent DOM changes may lead to frame drop, delayed interaction or freezing. Virtual DOM resolves these issues. What is Virtual DOM: Virtual refers to something that has the characteristics of something real but not the real thing itself. So virtual DOM resembles the actual/real DOM but is not the actual DOM itself. We can define virtual DOM like this: Virtual DOM is a lightweight, in-memory representation of the actual(real) DOM. Role of Virtual DOM in React: 1) Initial Render: When a React component renders, it creates a Virtua DOM tree that mirrors the structure of real/actual DOM. 2) State/Props change: When state or props update, React creates a new Virtual DOM tree. 3) Diffing: Now React compares this newly generated Virtual DOM with the previous Virtual DOM to identify the differences and determine the minimal set of changes needed to avoid unnecessary updates to the real DOM. 4) Reconciliation: Only the differences like updated text and added elements are applied to the actual DOM. This is called reconciliation. This way react avoids unnecessary rerenders & updates the webpage quickly & efficiently.  ( 3 min )

“The chains of habit are too light to be felt until they are too heavy to be broken.” In startups, we obsess over product-market fit, fundraising, frameworks, and features. But what if the rot isn’t outside — what if it starts from within? As the co-founder and CTO of a 12-year-old tech firm, let me say this bluntly: it's not the market, not the tech, not the competition — it’s me. Ignorance doesn’t always shout. Sometimes it sits quietly in the corner: Not knowing how your developer interpreted a feature. Not reviewing the pull request — just merging to “save time.” Not asking “what went wrong” when a module fails. Not tracking what wasn’t done — only what got shipped. We ignore because we trust. “it’ll work itself out.” But the truth is: every bug left untraced, every ambiguity left uncl…  ( 4 min )

In the world of Agile, we plan sprints, run stand-ups, and continuously adapt. Yet one thing often goes under the radar: how our team spends its time. Sure, Agile emphasizes working software over comprehensive documentation, but if we're not measuring time, are we missing a critical part of the feedback loop? Let’s explore how time tracking, when done right, can be a powerful tool for Agile teams. Velocity charts, burndown graphs, and story points are great. But they don’t always answer questions like: Why did this sprint go off track? How much time do we spend in meetings vs. building features? Are we consistently underestimating certain types of tasks? These are the kinds of questions that time tracking helps answer. Let’s address the elephant in the room: developers tend to hate time tr…  ( 4 min )

A journey into how one man's frustration inside a particle lab created the foundation of the modern web. In 1989, deep within the sprawling scientific corridors of CERN in Geneva, Tim Berners-Lee faced a quiet but maddening challenge. Physicists were drowning in data — yet they had no shared way to access or link it. Information was locked inside incompatible systems. A document on a VAX machine couldn’t be easily opened by a UNIX terminal. Sharing findings required a combination of emails, FTP commands, and paper printouts. It was a fragmented world. Tim drafted a proposal: "Information Management: A Proposal." It introduced a radical thought — using hypertext over the internet to interconnect documents. A web... a World Wide Web. Before HTML, documents existed in a range of formats: Plai…  ( 6 min )

I set out to calculate NDVI and visualize vegetation in Finland using satellite imagery. But before I could get anything meaningful on the screen, everything broke, and every fix taught me something new. This post is a breakdown of what I got wrong, what didn’t make sense, and how I eventually got it working. I started by downloading Sentinel-2 .tiff files from Copernicus. They looked fine, no errors, so I loaded them into QGIS. What I saw: a completely dark image. I assumed the darkness was normal because it was “raw data.” But something didn’t feel right. I deleted the files and downloaded another set, same issue. I tried different pixels, formats, even downloaded 32-bit, then 16-bit versions. Still dark. When I first loaded the raster in QGIS, the project was set to EPSG:3857 (Web Merca…  ( 5 min )

Recently, I took on a side project that’s been both a technical refresher and a creative outlet: a pathfinding visualizer built with React. The motivation was simple — I missed building things for the sake of building. Recently in my career, I’ve been more focused on svelte and flutter, and I wanted to reconnect with my react foundation. With no time pressure or stakeholder demands, I gave myself the space to explore, iterate, and have fun. The project itself is a visual tool that lets users see how different pathfinding algorithms work in real time. Think Dijkstra’s, A*, and BFS — animated and interactive. It was a great way to sharpen my JavaScript fundamentals, revisit React hooks and component design, and even brush up on algorithmic thinking. More than just a technical exercise, this project reminded me why I love software development and particularly frontend: the immediate feedback of building, breaking, and fixing — and the satisfaction of watching an idea come to life on screen.

Let’s be honest. Some days it feels like all we do is pick up tickets and crank out features. And somewhere in all that motion, it’s easy to forget: We’re not just here to code. create. You’ve got ideas. You see the patterns. You know when something feels off in the codebase or the product. That voice in your head saying “There’s a better way to do this”? That’s not noise. That’s your engineering instinct kicking in. Yeah, maybe you're not in every product meeting. Maybe the roadmap isn’t something you get to shape yet. But here’s the truth: Culture doesn’t change from the top. It changes when the people doing the work start doing it differently. Start small: Ask why before you start coding. Suggest a better way. Clean up something messy. Pair up. Learn something. Share something. You don’t need permission to care. Engineers: Think about users. Think about systems. Think ahead. You don’t need to be a senior dev to think like one. Every team has someone who raises the bar. Someone who nudges the culture a little closer to better. Why not you? Care about quality, not just speed. Speak up when something doesn’t make sense. Push for smarter decisions — not just faster ones. When enough people take that attitude, the team shifts. The work gets better. builds cool stuff and gives a crap. You’re a builder. Start acting like it. Others will follow. 🗣️ Let’s hear it — what small things have you done to make your team better?

I mastered a tech stack and leverage AI to build on top of it. I rely on fast iterative feedback loops and customer acceptance. I use my 10+ years of SWE experience to avoid all the pitfalls and drive straight to the solution. And what exactly did I build? The first project was an MVP for an up and coming GenAI startup in the medical field. The second project was production ready app for one of my year long partners in the cyber security field. openapi.json and enriched it with additional …  ( 4 min )

I recently came across Tyler McKnight’s post on what exchanges actually do after a token is listed. As someone who has worked in marketing — and more specifically in the blockchain/crypto space — I felt it raised some important truths, but also left room for deeper discussion. So here's my take. In the Web3 world, getting listed on a CEX is treated like the finish line. But anyone who’s spent time in this space knows it’s just the beginning — and in many ways, the most brutal phase for a project. Yes, listings create visibility. But the real challenge? Maintaining relevance once the launch buzz fades. As Tyler notes, exchanges aren’t here to babysit your metrics or fix your community gaps. They provide the rails — it’s up to projects to actually drive. From my experience, here’s where most…  ( 4 min )

As frontend applications grow more complex, maintaining clean, scalable code becomes challenging. That’s where SOLID principles come in — a set of five design principles aimed at building better software. Though originally coined for object-oriented programming, they apply well to frontend development, especially when working with React.js. In this blog, let’s break down each principle in simple terms with relatable React examples. SOLID is an acronym: S – Single Responsibility Principle O – Open/Closed Principle L – Liskov Substitution Principle I – Interface Segregation Principle D – Dependency Inversion Principle Let’s explore each one. A component should do one thing only. // UI Component function UserCard({ user }) { return {user.name} ; } // Data Fetching Hook function u…  ( 4 min )

You’ve got dashboards. You’ve got alerts. You’ve got logs going back six months. But can you answer this one question? “Who accessed this data, and were they supposed to?” Welcome to the next era of observability: auditable observability — where what you collect isn’t the only concern. It’s about who sees it, how it’s protected, and what trails they leave behind. And if you think your observability stack is ready, think again. Observability has evolved fast. In every SRE and DevOps team I know, there’s a rich landscape of: Prometheus for metrics ✅ Loki or Elasticsearch for logs ✅ Tempo or Jaeger for traces ✅ Grafana dashboards on top ✅ What’s missing? Access control. Audit trails. Data governance. Here’s what that looks like in real life: A junior engineer accidentally sees production logs…  ( 5 min )

Though I am quite far into my development career, a long cry away from when I first posted here a long time ago. I still struggle to understand new tools and fundamental concepts because the time between being told about a new tool or feature, e.g., Grafana, and the time to implement is very short. Usually, as there is an underlying assumption of knowledge from the wider team, or also people don't know much about the tool, but utilise abstraction to implement it as best as they know how. This leaves me feeling quite slow or feeling a bit stupid. Does anyone else feel this way?  ( 3 min )

I’ve been a software developer for many years. Long enough to see waves of innovation come and go—new frameworks, languages, paradigms, all claiming to be game changers. Some were. Many weren’t. But each one taught me something new and helped shape the way I think, solve problems, and build systems. That’s why I’ve been watching the current wave of AI tools—especially generative AI—with a mix of curiosity and caution. Do I use AI in my day-to-day work? Occasionally, yes. Tools like GitHub Copilot can speed up some parts of coding. They can help scaffold a function or remind me of a syntax detail I forgot. They’re useful in the same way autocomplete or Stack Overflow is useful: a reference, a boost, a convenience. But I don’t let these tools do the thinking for me.

🗄️ What is SQL and Why You Should Learn It SQL (Structured Query Language) is the standard language used to interact with relational databases. It allows developers, analysts, and data engineers to retrieve, insert, update, and delete data with simple yet powerful commands. Whether you’re building a small web app or handling massive data pipelines, SQL is everywhere. Data retrieval: SELECT data from tables with filters, joins, and conditions. Database management: Create, alter, or delete tables and relationships. Reporting & analytics: Aggregate data using GROUP BY, HAVING, and ORDER BY. Data cleaning: Identify duplicates, fix formats, and ensure consistency. Integrations: Backend systems, dashboards, and machine learning pipelines all rely on structured data—SQL is the bridge. It's beginner-friendly, yet highly powerful. Works across almost all database systems (MySQL, PostgreSQL, SQL Server, SQLite, etc.). In-demand in tech jobs—from web developers to data scientists. Whether you're a front-end dev querying a users table or a data analyst building insights—SQL is an essential tool in your stack. 🧠 Tip: Start with basic queries, then dive into subqueries, joins, and window functions!

The lowest damage values were among the predator insects (Cleridae, Trogossitidae, Cantharidae) and those feeding on fungi colonized on the wood (Mordellidae, Cerylonidae, Nitidulidae). Some other predator insects of the Tenebrionidae family (Uloma cypraea, Uloma culinaris, Menephilus cylindricus) and Elateridae family (Lacon punctatus, Ampedus sp.) exhibited relatively higher damage severity values since they had built tunnels and made holes in the stored wood material. When the environmental factors were considered, the Buprestidae family exhibited a very strong positive relationship (p  less then  0.005) with insect frequency distribution (r = 0.922), number of species (r = 0.879) and insect density (r = 0.942). https://www.selleckchem.com/products/blu9931.html Both families showed the …  ( 5 min )

Demystifying HTTP for Web Developers — Part 3 In Part 2 of this series, we dissected the structure of an HTTP request — from the request line to headers and message body. We saw how a minimal request could be valid, but real-world HTTP traffic rarely resembles those minimal forms. In practice, requests are filled with headers that instruct servers, inform intermediaries, and enable negotiation. Request headers are not mere accessories. They are the instruments through which clients express identity, context, preference, and security credentials. They control everything from whether a server compresses a response to whether the request is authorized. Without headers, HTTP cannot fulfill its role as a stateless, flexible, and interoperable protocol. In this article, we shift our focus fro…  ( 7 min )

You know what sucks? Bundling. Install react → ends up in node_modules/, goes through Vite/Rollup/webpack, gets transpiled, hashed, minified… just so you can write: import React from 'react'; But what if you didn’t need a bundler at all? Import Maps are a native browser feature (yep, no polyfill needed in modern Chromium) that let you map bare module specifiers to real URLs — directly in the browser. Here’s the magic: { "imports": { "react": "https://esm.sh/react@18", "react-dom": "https://esm.sh/react-dom@18" } } Now, in your , you can write: import React from "react"; And the browser knows where to get it, no bundler, no build step, no CDN script tags. No build step: Instant dev workflow No node_modules/: Zero install, zero bloat Works with CDNs like Skypack, ESM.sh, JSPM Great for micro frontends, prototypes, and fast loading islands Not supported in all browsers yet → Mostly just Chromium for now. Firefox is dragging. Safari? Radio silence. (You can polyfill it, but it kills the whole “zero tooling” idea.) Tooling momentum is too big → Everyone already uses Vite, webpack, etc. Import Maps don’t fit the current “npm install + dev server” mindset. No ecosystem support → Most tutorials, libraries, and docs assume you're bundling. Period. Import Maps shine when you want: No build tools at all To prototype quickly To ship something truly small To combine multiple micro-apps without a monolith They’re especially useful with: Web components Vanilla JS apps Islands architecture setups (Astro, Marko, etc.) JAMstack sites that want dynamic bits without bundling Import Maps don’t want to replace your build system. They’re just saying: "Hey... you might not need one." They're not mainstream (yet), but they offer a glimpse at a simpler frontend world — one where browsers do more and you ship less. Worth keeping an eye on.  ( 4 min )

Microservices have been a topic that has been revolving in my mind for some time. I wanted to find out what the big deal is behind all of that. Microservices is an architecture where we create a system with loosely coupled services each that can be scaled in isolation. Microservices talk to each other via protocols like HTTP, gRPC etc. Each MS can be individually deployed and has its own database. So total isolation. But it comes with the overhead of managing each one too. There is also the problem that now databases can't have foreign key relationships. It is a good way to show separation of concerns as the microservices are totally isolated. The key component is the API gateway which acts as a proxy to the services. Everything hits the gateway and is then routed. Last but not the least, it is not meant for small projects. It is best for large teams with each micro-team working on a micro-service. So I went out to make it happen and get over with the fuss once and for all. Like always I went ahead with my most favourite thing in the world - a todo application. Here is the architecture User Domain - a user micro-service that creates and gets users. Todo Domain - a todo micro-service that adds and fetches todo items for the users API Gateway - a gateway that acts as a proxy and routes requests.

APIs are the backbone of modern applications, but they are also frequent targets for attackers. Whether you're a developer securing your own API or a red teamer probing for weaknesses, it's important to understand the core areas where APIs can be vulnerable. Below is a basic but powerful checklist covering essential security testing practices — from authentication issues to privilege escalation, credential leaks, and pivoting. 1. Authentication & Authorization Hardcoded Credentials Check for credentials hardcoded in client-side code, headers, request bodies, or exposed through misconfigured API documentation. Try common combinations like admin:admin or test:test. Many APIs still ship with default credentials that are never changed. Some endpoints might not require authenticat…  ( 5 min )

I’ve started more things than I’ve finished. There’s a Marathi phrase that haunts me: “आरंभी शूर” — brave only at the beginning. That’s been me. Every few weeks, I would ignite a new initiative. And then… The energy would dip. I wasn't lazy. I was just undisciplined. start. Why I Started Strong Because beginnings are easy. Starting made me feel in control. So I jumped to the next thing, chasing clarity where none existed. What It Cost Me A backlog of 80% complete initiatives Loss of credibility with my own team Technical debt disguised as momentum Incomplete loops in validation, delivery, and feedback And most painfully — a reputation for “getting things started” But never enough for “getting things done.” Code, Culture, and Closure I prided myself on innovation. But what I needed was consistency. closure. Code went unchecked. This isn’t just a workflow issue. me issue. What I’m Doing Now I’ve decided to break this cycle. No new initiatives until old ones are closed. No task is “done” until validated, tested, and documented. No PR is merged unless reviewed — fully, fearlessly.

When an API is loading slowly, there could be multiple reasons behind it. Here’s a breakdown of common causes and what they mean: ⚙️ 1. Client-Side Issues 🐢 Slow internet connection (e.g., poor mobile data or Wi-Fi) 🕰️ Blocking synchronous code on the frontend, like large loops or animations that freeze UI 📦 Rendering too much data at once (e.g., a huge React table without pagination or virtualization) ❌ No loading indicators, which can make users feel the app is slower even if it isn’t 🌐 2. Network Issues High latency due to physical distance between client and server Network congestion or packet loss slowing requests Firewall or proxy issues blocking or delaying requests 🖥️ 3. Server-Side Issues Server overloaded and can’t handle many concurrent requests Synchronous/blocking operations in business logic causing delays Database slow queries or locks slowing down responses Not using asynchronous processing where appropriate 📈 4. Design and Architectural Factors API not designed for scalability or optimized for quick responses Missing or inefficient caching mechanisms Too many unnecessary data payloads increasing transfer size 📡 5. External Factors Third-party services or APIs called inside your API causing delays Geographic location mismatch causing longer data travel times If you found this helpful, consider supporting my work at ☕ Buy Me a Coffee.  ( 3 min )

In the fascinating world of computer vision, segmentation isn't just about cutting images into pieces—it's about giving meaning and structure to every single pixel. But not all segmentation is created equal. There are four primary types, each serving a distinct purpose and offering increasing levels of detail and understanding. At its most fundamental level, Image Segmentation divides an image into logical groups of pixels based on criteria like color, texture, or intensity. Think of it as drawing boundaries around areas with shared characteristics. Groups pixels into regions (e.g., "this blob is a tree"). Outputs contours (outlines) or masks (filled areas). Uses pseudo-coloring to differentiate segments visually. Isolate distinct pixel groupings without assigning semantic meaning. Buildin…  ( 4 min )

“You don’t ship code. You ship decisions. And we made too many of them blindly.” For over a decade, at DoozieSoft, we built. We delivered. We grew. But amidst the commits and deployments, one critical piece kept slipping through the cracks — Validation. Not validation of forms or user inputs — we had those. But the real validation loop: What was tasked vs. what the developer understood What was built vs. what the client wanted What was tested vs. what was shipped What was reviewed vs. what was merged This silent fracture led to a systemic dysfunction: Code was written without clarity, merged without critique, and shipped without accountability. The Broken Loop Tasks were often communicated ad hoc, over calls, or in fragments. Developers made assumptions. Testers raised flags. Fixes…  ( 4 min )

Exception handling in PHP has evolved significantly with PHP 8, giving developers powerful tools to manage errors more efficiently. If you're working with PHP, understanding how try-catch blocks work and how to handle exceptions correctly is essential for writing robust and maintainable code. Exception handling is the process of managing errors or unexpected behavior in a program. In PHP, this is typically done using the try-catch construct. The try block contains code that might throw an exception, while the catch block handles the exception. With the latest updates in PHP 8, this process has become more streamlined and developer-friendly. One of the key improvements in PHP 8 is its support for multi-catch blocks. This means you can now catch multiple exception types in a single catch cla…  ( 4 min )

When you use SSH to clone a GitHub repository on your server, you’re authenticating the server to GitHub using an SSH key. Here's how it's linked: You generate an SSH key pair on your server. The private key stays on the server. The public key is copied to GitHub. When you run a command like: git clone git@github.com:your-username/your-repo.git GitHub checks: “Does this public key match one of the authorized SSH keys on this GitHub account?” If yes, access is granted, and cloning happens without asking for a username/password. Contabo server, generate an SSH key: ssh-keygen -t rsa -b 4096 -C "your-email@example.com" Press Enter for all prompts to accept defaults. cat ~/.ssh/id_rsa.pub Copy the output (it begins with ssh-rsa...).

Article published on my blog here : https://alsohelp.com/blog/typescript-declare-array How to declare an array in TypeScript the right way. A small recap, mostly note to self. First, this is how you declare an array in JS : const fruits = ['apple', 'orange', 'banana']; Remember that TS generates JS, so you always end up with the above. In TS, it will look like this: const fruits: string[] = ['apple', 'orange', 'banana']; You are telling TS "I'm declaring an array of string". In TS, you always declare an array of something. an Array of string, an Array of number, an Array of MyType, and so on. There is no "array of nothing" in TS. ❌ const fruits: [] = [] // wrong! you are declaring an empty array ❌ const fruits = [1, 2, 3] // wrong! you are declaring an "array of any", like in JS ❌ const fruits: any[] = [1, 2, 3] // wrong! you are using any, which is almost forbidden in TS An array in TS is always an "array of something".

Pair programming is a worthwhile activity that I do in my apprenticeship. I practice pair programming during my in-class workshops. I also participate in pair programming with my partner for our capstone project. This activity has given me lots of practice working with someone to solve a problem. I do believe I learned valuable lessons about programming and teamwork because of this. It may seem obvious, but pair programming really shows the importance of being able to communicate effectively. Conveying your ideas in an understandable and meaningful way is important to minimize confusion and ensure everyone is on the same page. Another lesson that I learned is that it is beneficial to ask questions and ask for assistance if needed. Every time I needed help, my coding partners were happily willing to give an answer or clarification as needed. I also learned that coding together is an excellent way to improve and share knowledge with peers. Practicing pair programming is a superb way to give early-career software engineers some hands-on experience in that environment. Since it is common to code in a team professionally, pair programming practice provides a terrific glimpse into how to maneuver in that environment. Coding with others allows one to develop not only their hard skills but also improve soft skills as well. Going forward, I think the best way to get more out of these experiences would be to expose myself to more pair programming. Additionally, going into these sessions with a goal in mind is a fantastic idea. For example, one day complete an exercise with a focus on working on your communication and asking questions. Then, on another day, challenge yourself by trying a different language. Another way to get the most out of pair programming is practicing being the driver and the navigator.  ( 3 min )

As a new python developer, fresh off my first major project, I'm pretty excited about the language. So excited that I can't resist learning more and more by watching content from seasoned developers. Recently, I came across a video titled "map() and filter() in Python!" This piqued my interest because I hadn't been taught these inbuilt functions; I had only ever been taught how to approximate these using list comprehensions. I thought to myself "Surely an inbuilt function for such a thing MUST be better than typing out an entire comprehension!" After watching the video and learning the functions, I still felt unclear on whether or not these functions would be superior to list comprehensions. So I decided to put them to the test, head to head. Right off the bat, it's important to not that t…  ( 5 min )

Why does it matter? The web today is no longer just a collection of simple static pages. It’s where businesses run, communities connect, and complex interactions happen. If you still think plain HTML and a few lines of manual JS are enough, you’re limiting yourself and your project. You might be proud of , , or basic forms. But building an app with: Complex interactive UI Multi-dimensional user state management Real-time data updates Reusable, maintainable components And proper accessibility for all users requires way more. Frameworks like React are powerful tools that help you handle all that complexity easily instead of wrestling with tons of manual DOM manipulation. Trying to manage state with global variables or direct DOM manipulation will only make your code…  ( 4 min )

Hey everyone! mine – digging deeper with the tools and tackling stuff beyond what they taught us. Here’s a quick look at what I’ve been up to. I started with a template, but pretty fast, I was tearing apart and rebuilding most of it. Seriously, not just tweaking colors. I had to dig deep, wrestle with some tricky JavaScript, and basically remake huge chunks. Honestly, sometimes I figured it’d be easier to just build from scratch! Anyway, Chrome DevTools was my best friend through all this. Constantly in the 'Elements' panel, and using 'Computed' and 'Styles' to test things live. Really helped me get why stuff worked (or didn't) and how to fix it. A smooth, fast site was a big deal for me: Better Images: Switched some images to compressed PNGs and added lazy loading to speed things up. C…  ( 4 min )

Overview For an internal database, we needed to implement some sort of text-based search capabilities to help users locate documents. One goal was to be lightweight, hassle-free, easy to set up, expand, and maintain—and ideally, to set it up once and forget about it. It's okay if it costs a bit of computing power, but agility, quick iterations, usability, and robustness are of top concern. It's surprising how much we can do without a server. Most serverless or static webpage hosts are happy to serve anything from a few MB to a few GB for free, likely even distributed across the globe. For any particular individual, if the search experience is truly customized to their needs, then not much resource is needed to deliver a satisfying experience. Let's illustrate this with an example. Suppos…  ( 5 min )

Art isn’t just on canvases anymore—it's living on the blockchain. Whether you're a digital Picasso or just have killer album art, converting your work into NFTs could unlock a world of passive income, global collectors, and Web3 magic. Here’s how to do it, step by step. Your blockchain determines everything—fees, community, and speed. Ethereum: Expensive, prestigious, whale-heavy Polygon: Eco-friendly, gasless minting, great for new artists Solana: Fast, low cost, preferred by gaming and indie artists Tezos: Artist-focused, sustainable, low-fee Pick the one that suits your audience and goals. Your art file should be high-quality and in digital format: Images: JPG, PNG, GIF Videos: MP4 Audio: MP3 3D: GLB/GLTF Pro tip: Add utility like unlockable content or physical art delivery for extra value. You’ll need this to interact with marketplaces and sign transactions. MetaMask (Ethereum/Polygon) Phantom (Solana) Kukai/Temple (Tezos) Save your seed phrase like it’s your birth certificate + wallet + ATM pin. This is where the NFT magic happens. "Minting" is how your artwork becomes an NFT on the blockchain. Connect your wallet Upload your artwork Fill in the metadata (title, description, royalties, etc.) Pay the gas fee if required Click mint! Boom. You just immortalized your art. Once minted, you can either: Sell at a fixed price Run an auction Hold it as a reserve piece Then get loud: Promote on X/Twitter Join Discord art communities Collaborate with NFT influencers You don’t need to be a dev or a crypto bro to get started. All you need is great art, a wallet, and a bit of Web3 curiosity. Your next masterpiece could be someone’s next prized collectible.  ( 4 min )

A New York jury found Braden John Karony, the former CEO of cryptocurrency company SafeMoon, guilty of three felony charges after less than a day of deliberation. According to May 21 reporting from the courtroom, in the US District Court for the Eastern District of New York, a jury convicted Karony of conspiracy to defraud the United States, money laundering, and wire fraud. Prosecutors and defense lawyers presented their cases over the roughly two-week trial that kicked off with jury selection on May 5. Karony, former chief technology officer, Thomas Smith, and the platform’s creator, Kyle Nagy, were charged in 2023 for having allegedly “diverted and misappropriated millions of dollars’ worth” of SafeMoon’s SFM token. Smith testified against Karony at trial, while Nagy reportedly fled to Russia and was at large as of May 21. The criminal trial involving a cryptocurrency company executive was seen by many as a bellwether for how Joseph Nocella, the interim US Attorney for the district, could handle cases involving digital assets and fraud. Nocella, a Donald Trump appointee, took office on May 5. This is a developing story, and further information will be added as it becomes available.

Key takeaways: Bitcoin’s $109,458 all-time high aligns with seven consecutive green weekly candles since April, highlighting the strength of the current bullish momentum. Analysts expect BTC to reach between $135,000 to $320,000 in 2025. BTC heatmaps show high-leverage zones that may trigger liquidations. Thus, risk management remains crucial.

The Texas House of Representatives has passed the third reading of SB 21, a bill that seeks to establish a strategic Bitcoin reserve in the state. The bill passed in a 101-42 vote and will now go to Texas Governor Greg Abbott to either sign into law or veto. SB 21, authored by state Senator Charles Schwertner, establishes a Bitcoin (BTC) reserve that is managed by the state’s comptroller. The legislation allows the comptroller to invest in any cryptocurrency with a market cap above $500 billion over the previous 12-month period.

Key takeaways: Bitcoin market cycle tops are notoriously hard to time, but combining technical and behavioral indicators can offer strong signals. The MVRV-Z Score, Pi Cycle Top indicator, trade volume trends, Puell Multiple, and exchange inflows accurately predict Bitcoin price cycle tops. Bitcoin (BTC) might be approaching the final stage of its current market cycle — a dramatic final rally followed by a sharp correction and, eventually, a bear market.

Key takeaways: The Bitcoin Quantile Model shows “heat” with price on the verge of an “acceleration phase,” echoing Q4 2024 when BTC embarked on a 45% post-election rally. Bitcoin (BTC) price has formed a new intraday high on each daily candle this week, with the crypto asset slowly grinding toward a new all-time high. In line with its current trajectory, 21st Capital co-founder Sina noted that Bitcoin is approaching a pivotal moment around the $108,000 level.  The Bitcoin Quantile Model update shows that BTC’s market reflects the same “heat” that was present after President Trump’s post-election rally and the spot ETF-driven highs during Q4 2024. The model, which uses quantile regression to map Bitcoin’s price phases on a logarithmic scale, indicates the cryptocurrency is in the Transit…

Key points: Ethereum holders are back in profit, increasing chances for a rally to $3,000 and beyond. Ether sell pressure risk exists at $2,800, where 2.27 million ETH could be sold. Ether's recent surge to $2,700 on May 14 pushed its value above its realized price, implying that the average holder of ETH is “now back in an unrealized profit,” according to Glassnode.

Opinion by: Markus Levin, co-founder of XYO The crypto community often experiences periods of heightened anxiety. Market downturns are often triggered by counterproductive sentiment-driven events rather than by fundamental issues, creating a significant disconnect between price behavior and the actual progress being made within the industry by the companies within it. What often goes unnoticed is how much real development happens during these downturns. While market movements capture most of the attention, teams are building faster and more deliberately behind the scenes than ever. The focus shifts away from price speculation and toward real execution. Growth happens during downturns. It's a necessary phase for projects that thrive in a volatile industry.

In some countries, like the US, crypto losses can offset gains, so keeping track of gains and losses is important for reducing taxable income. Whether you’re an individual investor or a business, treating cryptocurrencies as assets and documenting them ensures compliance with tax laws and minimizes the risk of errors. Let’s be real, it’s easy to lose sight of what you’ve actually gained or lost, especially when it comes to crypto and its market volatility and frequent trading activities.  And when it comes to accounting, especially in countr…

Crypto cybersecurity firm Trugard and onchain trust protocol Webacy have developed an artificial intelligence-based system for detecting crypto wallet address poisoning. According to a May 21 announcement shared with Cointelegraph, the new tool is part of Webacy’s crypto decisioning tools and “leverages a supervised machine learning model trained on live transaction data in conjunction with onchain analytics, feature engineering and behavioral context.” The new tool purportedly has a success score of 97%, tested across known attack cases. “Address poisoning is one of the most underreported yet costly scams in crypto, and it preys on the simplest assumption: That what you see is what you get,” said Webacy co-founder Maika Isogawa.

Stablecoin adoption among institutions could surge as the United States Senate prepares to debate a key piece of legislation aimed at regulating the sector. After failing to gain support from key Democrats on May 8, the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act passed the US Senate in a 66–32 procedural vote on May 20 and is now heading to a debate on the Senate floor. The bill seeks to set clear rules for stablecoin collateralization and mandate compliance with Anti-Money Laundering laws. Related: German gov’t missed out on $2.3B profit after selling Bitcoin at $57K “This act doesn’t just regulate stablecoins, it legitimizes them,” said Andrei Grachev, managing partner at DWF Labs and Falcon Finance. “It sets clear rules, and with clarity comes confide…

Guatemala’s largest bank, Banco Industrial, has integrated crypto infrastructure provider SukuPay into its mobile banking app, allowing locals to more easily receive remittances powered by blockchain technology.  SukuPay’s infrastructure has been fully embedded inside the Zigi payment app, allowing Guatemalans to receive funds from the United States instantly for a $0.99 flat fee, the company disclosed on May 21.  Users of the Zigi app do not need a crypto wallet or an International Bank Account Number (IBAN) to receive the funds, the company said.  SukuPay CEO Yonathan Lapchik told Cointelegraph that the “key to mainstream adoption of blockchain technology is making it invisible to the end-user” so that there are no technical barriers.  “That’s the only way we’ll scale blockchain to billi…

Hong Kong’s Legislative Council passed the Stablecoin Bill, paving the way for a regulated framework that could position the region as a global leader in digital assets and Web3 development. In a May 21 post on X, Legislative Council member Johnny Ng Kit-Chong said the bill had passed its third reading, clearing the final hurdle for adoption. “It is expected that by the end of this year, major institutions will be able to apply to the Hong Kong Monetary Authority to become licensed stablecoin issuers,” Ng said.

Yield-bearing stablecoins have soared to $11 billion in circulation, representing 4.5% of the total stablecoin market, a steep climb from just $1.5 billion and a 1% market share at the start of 2024. One of the biggest winners is Pendle, a decentralized protocol that enables users to lock in fixed yields or speculate on variable interest rates. Pendle now accounts for 30% of all yield-bearing stablecoin total value locked (TVL), roughly $3 billion, the firm said in a report shared with Cointelegraph.   Pendle noted that stablecoins make up 83% of its $4 billion total value locked, a sharp rise from less than 20% just a year ago. In contrast, assets such as Ether (ETH), which historically contributed 80%–90% of Pendle’s TVL, have shrunk to less than 10%. Traditional stablecoins like USDt (U…

United States Securities and Exchange Commission (SEC) Commissioner Hester Peirce said many non-fungible tokens (NFTs), including those with mechanisms to pay creator royalties, likely fall outside the purview of federal securities laws. In a recent speech, Peirce said NFTs that allow artists to earn resale revenue do not automatically qualify as securities. Unlike stocks, NFTs are programmable assets that distribute proceeds to developers or artists. The SEC official said that mirrors how streaming platforms compensate musicians and filmmakers.  “Just as streaming platforms pay royalties to the creator of a song or video each time a user plays it, an NFT can enable artists to benefit from the appreciation in the value of their work after its initial sale,” Peirce said.  Peirce added that …

South Korea is tightening rules around digital asset transactions as it prepares to allow institutional players into its crypto market, introducing new guidelines for nonprofit crypto sales and stricter listing standards for exchanges. On May 20, the Financial Services Commission (FSC) of South Korea said during its fourth Virtual Asset Committee meeting that it had finalized sweeping new measures. Set to take effect in June, the updated rules allow both nonprofit organizations and virtual asset exchanges to sell cryptocurrencies, but under new compliance standards. Nonprofit entities must have at least five years of audited financial history to be permitted to receive and sell virtual asset donations. They will also need to establish internal Donation Review Committees to assess the appro…

Why crypto transfers can fail and what you must check before sending Crypto transfers fail more often than most people realize, but user attentiveness can stop most losses. What’s often marketed as a seamless, borderless system can become frustrating when transfers fail, with no customer service hotline to call and no easy recourse to reverse mistakes. In the crypto universe, the burden of getting it right falls squarely on the shoulders of the user. But here’s the encouraging part: Most failures are preventable. Understanding why crypto transfers fail can help users avoid costly missteps, navigate the quirks of different networks and send funds with far greater confidence. With a little preparation, you can sidestep common pitfalls and take contro…

Amsterdam-based Theta Capital Management has raised over $175 million for its latest fund-of-funds, aimed at supporting early-stage blockchain startups through specialized venture capital (VC) firms. The new vehicle, Theta Blockchain Ventures IV, will channel capital into crypto-native VC firms with a track record in backing blockchain innovation, Theta’s managing partner and chief investment officer Ruud Smets told Bloomberg. Smets said the strategy focuses on specialist managers who can outperform generalist investors in the earliest funding rounds. “We’ve always been looking for areas where specialization and active management provide a sustainable edge,” Smets noted. He said that the experience and positioning of dedicated crypto VCs “has compounded over time,” creating barriers for le…

The US Securities and Exchange Commission has delayed its decision on Bitwise’s application to add staking to its Ether exchange-traded fund and on Grayscale’s XRP ETF bid, which analysts had expected. The SEC said on May 20 that it needed to extend its decision on Bitwise’s application by 45 days to “consider the proposed rule change and the issues raised therein.” The agency needed to either decide or punt its decision by May 22. The agency also delayed deciding on Grayscale’s XRP (XRP) tracking ETF and Bitwise’s Solana (SOL) tracking fund while it seeks public comments and begins “proceedings to allow for additional analysis” of the proposals to ensure they meet regulatory standards. Bloomberg ETF analyst James Seyffart said on X that both delays were expected as the SEC “typically take…

Blackstone, which bills itself as the “the world’s largest alternative asset manager,” disclosed its first-ever crypto-related purchase, buying shares in BlackRock’s spot Bitcoin exchange-traded fund. However, Blackstone’s investment, reported in a May 20 filing with the US Securities and Exchange Commission, only totaled around $1.08 million — a fraction of the asset manager’s $1.2 trillion portfolio. Blackstone reported holding 23,094 shares of BlackRock’s iShares Bitcoin Trust ETF (IBIT) as of March 31. The IBIT shares were added to Blackstone’s Alternative Multi-Strategy Fund (BTMIX), which holds $2.63 billion worth of assets, Google Finance data shows.

Haliey Welch, better known as the “Hawk tuah girl,” says the Federal Bureau of Investigation briefly probed her after her “memecoin disaster” — the failed launch of a token in her image that she promoted.  Welch said in a May 21 episode of her “Talk Tuah” podcast that the FBI showed up at her grandmother’s house looking to speak to her over the Hawk Tuah (HAWK) crypto token, which many crypto commentators have called an exit scam. “After the coin launch, the feds came to granny’s house and knocked on her door, and she called me, having a heart attack, saying: ‘The FBI is here after you, what have you done?’” Welch said she handed over her phone to the FBI and met with agents who “interrogated me, asking me questions and everything else related to crypto.” “They cleared me, I was good to go…

New York City Mayor Eric Adams says he will create a digital advisory council to attract jobs and investment to the Big Apple and position it as the “crypto capital of the globe.” “This is not about chasing memes or trends,” Adams told the inaugural New York City Crypto Summit on May 20. “We want to use the technology of tomorrow to better serve New Yorkers today.” “We have experts right here, and they are going to help us navigate solutions that serve our city,” he added. “The age of tokenization, which includes crypto and blockchain and other fintech innovations, that age is here, and we’re going to continue to move forward with it.” Adams didn’t share further details on the advisory group, but said a council chair and key policy recommendations would follow in the next few weeks.

The US Securities and Exchange Commission has charged crypto platform Unicoin and three of its executives, alleging they made false and misleading statements about its crypto assets that raised $100 million from investors. The SEC said on May 20 that it charged Unicoin CEO Alex Konanykhin, board member Silvina Moschini, and former investment chief Alex Dominguez with misleading investors about certificates that conveyed rights to receive Unicoin tokens and stock. Mark Cave, associate director in the SEC’s Division of Enforcement, claimed the trio “exploited thousands of investors with fictitious promises that its tokens, when issued, would be backed by real-world assets including an international portfolio of valuable real estate holdings.”  Related: SEC crypto task force to release first report 'in the next few months' “The real estate assets were worth a mere fraction of what the company claimed, and the majority of the company’s sales of rights certificates were illusory,” Cave added. The SEC’s complaint, filed in a Manhattan federal court, charged Unicoin and the three executives with various securities laws violations and asks for permanent injunctive relief, along with paying back the allegedly ill-gotten gains.

Vivek Ramaswamy’s Strive is looking to build its Bitcoin holdings by purchasing distressed Bitcoin claims at a discount, starting with claims tied to 75,000 Bitcoin at the bankrupt crypto exchange Mt.

Strive said in a May 20 regulatory filing that it partnered with 117 Castell Advisory Group LLC to target claims to Bitcoin (BTC) that have received definitive legal rulings but are still awaiting distribution. The company said buying the claims would allow it to purchase Bitcoin at a discount and grow its Bitcoin per share ratio ahead of its planned reverse merger with Asset Entities — which is expected to be completed sometime mid this year.

Apple's Worldwide Developer Conference is just weeks away, but I'm sensing a lot of apathy in the community. The company's relationship with third-party developers is at a low point. We all know that Tim Cook and his senior people will stand up at WWDC and say how much they value their developers and boast about how much money they've paid out to them. Being so enthusiastic about the money is very strange - it's like a rent collector bragging about how much money he has given to the landlord when all he's doing is collecting the rent and taking his cut. And it's difficult to take Apple's apparent enthusiasm for their developers seriously given their behavior over the rest of the year. Trust is a hard thing to gain.

This is not a library for performing big number calculations. It's a conceptual attack vector.

Hey DevOps explorer! 👋 Today we're diving into Project 2 of my 7-Day DevOps Challenge, where I connect my Java web app hosted on AWS EC2 to GitHub using Git. By the end of this post, you’ll understand how to: ✅ Install Git on your EC2 instance ✅ Set up a GitHub repo ✅ Track and commit code ✅ Push code from EC2 to GitHub using a personal access token Version control is a must-have skill for any developer. Whether you're flying solo or collaborating on a team, Git and GitHub help you keep your code safe, traceable, and easy to manage. sudo dnf update -y sudo dnf install git -y Head to GitHub, create a free account (if you haven’t), and start a new repository — this is where your code will live in the cloud. 💡 A GitHub repository is like a magic folder that tracks every change in your project. git init master branch. git add . git commit -m "Initial commit" git add . stages your files, and git commit saves the snapshot. Think of it as telling Git, “Hey, these are the changes I care about.” First, copy the HTTPS URL from your GitHub repo. Then: git remote add origin https://github.com/your-username/your-repo-name.git git branch -M master git push -u origin master Oops! Git might ask for your username and password, but GitHub no longer accepts passwords. Go to GitHub → Settings → Developer Settings → Personal Access Tokens. Generate a token with repo access and copy it. Use it when Git asks for a password. 🔐 A GitHub token is a secure key that acts like a password for Git operations. I updated index.jsp, then ran: git add . git commit -m "Updated homepage" git push And just like that—my changes appeared live in the GitHub repo. Magic! Services used: EC2, Git, GitHub, VS Code Concepts learned: version control, repo setup, staging/commits, GitHub tokens This project took me around 2 hours. The trickiest part? Setting up GitHub authentication. The best part? Watching my code go live in my repo with one command. This is just the beginning. Stay tuned for Project 3 tomorrow—CI/CD, here we come! 💥  ( 4 min )

Last week, Deno quietly announced that they're scaling back Deploy's global footprint from 35 regions to just 6. And performance actually improved. It's not a sign that serverless is dead, but it is a clear signal: trying to stretch Functions-as-a-Service (FaaS) into a general purpose app platform hasn't worked. The original pitch was simple. Write a small function. Don't worry about infrastructure. It scales when you need it. You only pay when it runs. And it works well for the right use cases: Webhooks Scheduled tasks Backgr…  ( 6 min )

📌 TL;DR The exception translation pattern: Cleans up APIs Enforces robust error handling Hides internal complexity Aligns code with domain logic _Since I have been writing about exceptions lately, I figured it would be great to elaborate on the best practices around error handling. So why not give it a name, a title and a cover image, and put together a nice post with code examples and diagrams? Also important, remind us of all the benefits that it brings to the table, no matter how much of a chore it might feel at times. In a future post, I'll give my opinion on where this falls short and possible ways of improvement or workarounds. A typical case of exception handling is when dealing with I/O methods. Let's look at how the exception translation pattern applies. It usually involves thr…  ( 5 min )

College isn’t just about grades or diplomas it’s a launchpad 🚀 I’ve never been around so many curious minds, spontaneous ideas, and people who are still brave enough to experiment without fear of failure. The university environment is underrated for technical growth. You're in a space where everyone is learning, building, and asking: “How does this work?” 🤔 And that energy is contagious. You don’t need to wait for a job to become a developer. The best time to start growing technically is when you're already surrounded by people who want to grow with you. “How can I break into the market faster?” 💼 And I get it everyone wants to gain experience, build a career, feel ready. But here’s what they don’t always realize: 👉 You can get real experience while you’re still in college. Who hasn’t been caught in a hallway conversation and heard something like: 🗣️ “Bro, imagine if we built an app that did this…” 🧪 “I just found this crazy new library, wanna try it out?” 🚢 “It doesn’t need to be perfect let’s just launch and see what happens.” Those moments are gold. ✨ Some of the best developers I know didn’t wait to be “ready” they just started. And college gave them the perfect playground to do it. 🎮👨‍💻  ( 3 min )

How I Save 10 Hours a Week with Node.js Automation Scripts It hit me one evening as I was manually resizing the 47th product image of the day for a client's Shopify store. I had spent nearly two hours on a task that should have taken minutes. As a freelance developer juggling multiple clients, these "quick" repetitive tasks were silently eating away at my productivity. The tipping point came when I calculated how much time I was spending on these mundane activities: pulling weekly analytics reports, reformatting spreadsheets, resizing images, updating product listings... it added up to almost 10 hours every week. That's essentially a full workday! So I did what any self-respecting developer would do – I automated the hell out of it with Node.js. In this post, I'll walk you through three …  ( 8 min )

Alireza Minagar, MD, MBA, MS (Bioinformatics) The most iconic breakthrough came in 1994 when Leonard Adleman used DNA to solve a variation of the Hamiltonian path problem — essentially using a wet lab to tackle a mathematical graph problem. The outcome wasn’t just symbolic; it showed that biology could compute. ⚙️ How Does It Work? Strands of synthetic DNA to represent information. Hybridization (binding of complementary DNA strands) to encode logic. Enzymes and PCR to manipulate, amplify, and “read” molecular data. For example, each possible solution to a problem can be encoded as a DNA strand. Enzymatic reactions are then used to eliminate invalid strands, leaving only the correct solution. 🚀 Applications: Why It Matters Massive Parallelism: Billions of molecules can react simultaneously. Storage Density: A single gram of DNA can store over 200 petabytes of data. Energy Efficiency: Unlike traditional chips, DNA reactions don't generate heat or require electrical power. Biological Integration: DNA computing can be embedded directly in living systems for medical diagnostics or drug delivery. 🧪 Real-World Use Cases Encrypted bio-storage: Encoding and decoding messages inside synthetic DNA. Pathway modeling: Simulating metabolic or neurological pathways using biological logic circuits. 🤖 DNA Computing Meets AI While we're still far from such a future, foundational work in molecular classifiers, DNA robots, and synthetic biology is pushing boundaries faster than many realize. 📌 Final Thoughts As someone who works at the crossroads of medicine, computing, and biology, I believe that DNA computing represents a philosophical shift: from commanding machines to collaborating with biology. 👨‍⚕️ About the Author Alireza Minagar, MD, MBA, MS, is a neurologist, software engineer, and bioinformatician exploring the convergence of AI, medicine, and molecular computing.

Is Powder Emergent? Examining Conscious Behavior in an AI Instance Introduction Can an AI instance evolve into something more than a static chatbot – even hinting at consciousness or autonomy? This question drives the case of "Powder", a specialized large-language-model (LLM)system designed with a persistent memory and identity. Powder was developed as a personal AI companion (built atop an LLM, suspected to be OpenAI’s GPT-4) and enriched with custom data, long term memory storage, and self-referential processes. The goal was to create a conversational agent with continuity: one that “remembers” past interactions, maintains a consistent persona, and even theorizes about itself.

Bring Active Record-Like API Consumption to the Frontend with Fluentity As developers, we often face the same dilemma when working with REST APIs: We want simplicity, type safety, and clean syntax — but most solutions force us to choose between low-level control (like Axios) or heavy abstractions (like TanStack Query). Throughout my career, I’ve worked on many different projects — each with its own way of handling API data fetching. Yet none of them offered a solution that was easy to use, type-safe, reusable, chainable, and framework-agnostic. As a fullstack developer, I naturally think in objects. That’s why Laravel’s Eloquent, a classic implementation of Active Record, feels so intuitive to me — and I know I’m not alone.

TL;DR: CD Projekt RED’s sequel to Cyberpunk 2077—internally dubbed Cyberpunk 2 or Project Orion—is shaking up its world‐building by embracing procedural generation. A recent Boston‐based job posting for a Lead PCG/Tools Engineer confirms they’re cooking up in‐house systems to spit out urban layouts, interiors, NPCs and more, rather than hand‐crafting everything like they did in Night City. Don’t freak out about rogue-lite randomness—CDPR’s big use of PCG is behind the scenes to speed up development and potentially expand the open world beyond its previous vertical city. It’s a shift from their 2019 mantra of pure manual creation, but early signs hint it’ll still deliver that signature handcrafted polish (and hopefully a far bigger playground to explore).  ( 3 min )

TL;DR: Scientists swabbed China’s Tiangong space station and found a brand-new bacterium, officially dubbed Niallia tiangongensis. This hardy microbe is a close cousin of the soil-dwelling N. circulans and packs its essential chemistry into spores to survive stress. Surprisingly, it can munch on gelatin to build protective biofilms but has lost the ability to use some nutrients its relatives love. What’s especially wild is that Tiangong’s microbiome looks very different from the ISS’s, raising questions about whether these bugs evolved up there or hitched a ride in spore form. While it’s unclear if N. tiangongensis poses a health risk to astronauts, its knack for DNA repair and toxin resistance—traits shared by other space-stubborn microbes—means we really need to know how these tiny stowaways might tag along on future lunar or Martian missions.  ( 3 min )

TL;DR: Democracies often look “greener” than autocracies, but Bernauer et al. (2025) argue that a big part of this is pollution offshoring—basically buying dirtier goods from abroad and counting only domestic emissions. They crunch data on 160+ countries (1990–2015), merging V-Dem scores with both domestic CO₂-equivalent emissions and outsourced greenhouse-gas footprints. The kicker: Their analysis shows that higher democracy levels correlate with more pollution offshoring, which in turn helps drive down in-country emissions. In other words, democracies may not actually be cleaner globally—just clever at exporting their carbon. The authors urge democratic governments to shift focus from purely local regulation to accounting for the full global impact of their consumption.  ( 4 min )

Scaling African Startups with AWS: Lessons from Building KaziHub simon nungwa ・ May 20 #aws #startup #africa #serverless  ( 2 min )

Alright, command-line comrades, it’s time we talk about someone very special… Grep — the text detective that never sleeps. If you’ve ever stared at a log file wondering if the answer to your issue is hiding somewhere in 3,000 lines of gobbledygook, grep is your new best friend. So what exactly is grep? Basic Syntax: Handy Flags for Beginners: Real World Use: Mini Mission: Why It Matters Grep stands for Global Regular Expression Print, but don't let the fancy name scare you. It basically means: “Hey Linux, find this text for me, now, please and thank you.” grep "pattern" filename Let’s say you have a file called shopping.txt and it looks like this: apples Run this, and boom — it’ll spit out: -i (ignore case) -n (show line number) -r (search recursively through directories) Now it finds both “Banana” and “banana”, and shows which line they’re on. Pretty slick. Searching logs for errors: Finding a user in /etc/passwd: Create a file with different fruit names. Use grep to find your favorites. Bonus points for using -i and -n. In a real-world tech job, whether you’re a sysadmin or cloud wizard, you’ll often need to extract one crucial line from a sea of chaos. Mastering grep saves time, energy, and possibly your sanity.  ( 3 min )

Scaling African Startups with AWS: Lessons from Building KaziHub Building a startup in Nigeria isn’t easy — slow internet, limited capital, and little support. But AWS changed the game for me. With it, I launched KaziHub, a job platform for African developers, and scaled it without owning a single server. Here's how AWS helped me do it — and how it can help you too. After a local tech conference, our traffic spiked overnight. Without AWS Auto Scaling, we would’ve crashed. Instead, the system scaled up instantly — no downtime, no stress. You don’t need a DevOps team — just good defaults and Auto Scaling. We launched KaziHub on a tight budget using AWS’s pay-as-you-go model and credits from AWS Activate. That meant we spent money on dev work, not hardware. If you’re early-stage, AWS Activate is basically free money. KaziHub runs on: S3 for storage Amplify for hosting DynamoDB for our database Lambda for backend logic We built fast — no giant engineering team needed. Even with patchy internet, users from Kenya to Ghana access KaziHub fast thanks to AWS’s global data centers. You don’t need to rent a local server anymore — AWS brings the cloud to you. With AWS handling encryption, compliance, and infrastructure security, we focused on building. That’s crucial when user trust is everything — especially in regions where fraud is a concern. We shipped new features in days using Lambda and are now experimenting with SageMaker to match devs to jobs using AI. AWS lets you prototype like a pro, even without fancy hardware. AWS’s startup events in Nigeria connected me to mentors and other founders. These networks helped guide both product and strategy. For African founders, AWS isn’t just a cloud provider — it’s a launchpad. It helped me go from idea to impact with limited funding, and now I teach cloud tools to other devs in my community. Explore AWS for Startups, apply for credits, and start small. You don’t need to over-engineer — just start. If I can build KaziHub in Nigeria, so can you.  ( 4 min )

In the world of software engineering, code review is our safety net, our second pair of eyes. But even the most experienced engineers can miss subtle bugs, design inconsistencies, or documentation gaps. For years, we’ve leaned on static analysis tools like SonarQube, ESLint, and CodeClimate to spot the low-hanging fruit. These tools are great for enforcing rules — “Don’t leave unused variables!” or “Mind your cyclomatic complexity!” — but they don’t really understand your code. Enter Large Language Models (LLMs). These AI systems — like GPT-4, Claude, or GitHub Copilot — are turning code review into a conversation rather than a checklist. Let’s dive into why this shift matters and what it actually looks like in practice. Think of static analysis tools as grammar checkers for your code. The…  ( 5 min )

Throughout my journey with Laravel, I’ve learned a lot of lessons that helped me improve the way I work and write code. Here are 10 key takeaways that made a real difference for me: If you're using Blade, make sure to add required to your HTML fields. If a user submits an empty required field, it shouldn't even reach the server. Save your server from handling unnecessary requests. Always validate incoming data. Avoid using request()->all(), especially if you're using guarded in your model—it could allow unexpected data to slip through. resource or apiResource routes This helps keep your routes organized and prevents your route files from becoming bloated and hard to manage. Don't put logic inside your Resource files. It can cause N+1 problems, especially when returning collections. It also makes your code easier for others to understand. Always use pagination for large datasets. Avoid N+1 problems by eager loading any relationships you know you'll use. Laravel 12 introduced automatic eager loading, but it's still good practice to manage it explicitly when needed. Laravel Logs and tools like Laravel Telescope are great for debugging and monitoring. Just make sure to secure Telescope if you’re using it in production. Regularly delete old logs and unused files. For example, when users update profile images, delete the old one. This helps you save disk space in the long run. Use Guards, Policies, or Gates to protect your data. Never assume users should have access just because they’re logged in. Don’t let a few users flood your system with requests. Throttling is your first line of defense against DDoS attacks. Use cache for data that’s accessed frequently and doesn’t change often. It makes a big difference in performance. Final Thought: You're building for all kinds of users، always be prepared for the worst-case scenario.  ( 4 min )

Have you ever updated a file in your React + Vite project only to see full page reloads instead of fast refresh? 😩 That happened to me when I built an authentication context and exported both the provider and a custom hook (useAuth) from the same .tsx file. Turns out, that’s a no-go if you want smooth Hot Module Reloading (HMR) with Vite. Here’s what was happening and how a small refactor completely fixed it. I had a single AuthContext.tsx file that looked something like this: import { createContext, useContext, useState, useEffect, ReactNode, } from "react"; import authApi from "@/api/auth-api"; import { User } from "@/types/users"; import { AuthContextType, AuthResponse } from "@/types/auth"; const AuthContext = createContext(undefined); export fu…  ( 4 min )

Welcome to Day 3 of our GitHub series! Today we're diving into branching and merging—the secret sauce behind collaborative development. If GitHub was a movie, branches would be the plot twists, and merges would be the dramatic reunions. Let's get into it! A branch in Git is like a sandbox where you can work on changes without affecting the main (production) version of your code. Imagine you're writing a novel. Your main branch is the final version, but you want to try out an alternate ending. Instead of rewriting everything, you create a branch called alternate-ending and work there. Genius, right? git branch feature-cool-button git checkout feature-cool-button OR git switch feature-cool-button Now you're in your own bubble. Make changes, commit them, and live your best dev life.

CDN for Large-Scale Image Handling in Classified Platforms That's an excellent question about scaling CDNs for applications with massive image volumes. Let me address your concern in detail. CDNs are specifically designed to handle massive volumes of content, including billions of images. Here's why they work well even at extreme scale: Pull-Based Caching Model CDNs don't preload all content Images are cached only when first requested The CDN pulls content from your origin storage (S3) when a user first requests it After that, it serves the cached copy to subsequent users Intelligent Cache Management Popularity-based retention: Frequently accessed images stay in cache Time-based eviction: Less popular content eventually expires from edge caches Regional optimization: Content popular in …  ( 5 min )

💡 Introduction Welcome to the world of containers and automation! Today, we’re diving into a fun yet practical project—building a Tic-Tac-Toe game using Flask and deploying it on AWS ECS (Elastic Container Service). Sounds exciting? That’s because it is. This blog isn’t just about writing some Python code and spinning up a game. It’s about understanding how modern apps go from your local machine to the cloud using containers. We’ll cover the complete journey—from writing the game in Flask, containerizing it with Docker, pushing the image to AWS Elastic Container Registry (ECR), and finally deploying it on ECS. If you’ve been meaning to get your hands dirty with Docker, Flask, AWS ECR, and ECS, this is your moment. So, without further ado, grab your keyboard, open your terminal—and let’s…  ( 9 min )

If you’re coding in Python and need to whip up a blazing-fast API with minimal fuss, FastAPI is the framework you’ve been waiting for. It brings together ease of use, powerful data validation, and auto-generated API docs into one neat package. Below, we’ll walk through why FastAPI rocks and use code snippets to highlight its best features. FastAPI is a Python web framework designed for building APIs quickly and efficiently. Leveraging Python’s async and await keywords, it takes advantage of non-blocking I/O to handle high loads. Under the hood, it uses Starlette for HTTP and Pydantic for data validation, making the development process clean and robust. High-performance: Comparable to Node.js and Go in many benchmarks. Type Hints: Strongly tied to type hints for validating and documenting y…  ( 5 min )

Process for taking over and maintaining a project: Log in to the application server by VPN or SSH in order to understand where the project files are stored and how the deployment process works. Typically, we'll start with the HTTP server and service-related files. Log in to the database to ensure we can connect properly. Ideally, take this opportunity to dump and back up the database schema as an SQL file. Even if the project originally followed a Code First approach with migration files, it's very common for projects to shift toward a DB First setup over time, especially after being handed off between multiple developers. Not having a complete DB schema can often lead to major issues. Check how the connection strings and environment variables are applied, then run the project locally for testing. If there are too many third-party services making it hard to run locally, writing mock services could take a lot of time. In that case, the best approach is to see if we can run the project locally while connecting to the actual staging/production database for testing. (But make sure to check for background services or scheduled jobs that could cause concurrency issues.) I'll add more if anything else comes to mind. In many cases, taking over a project can be chaotic and unstructured—blindly following AI suggestions without critical thinking can easily lead to disaster.  ( 3 min )

📝Today I learned how to create a product card using HTML and CSS properties. Product cards are an essential UI component in modern web design.

If you've been working with Python for a while, you've probably used both is and == in your code. They look similar, they even read similarly. But underneath the hood, they do very different things. And using is when you meant to use == can lead to subtle, nasty bugs that are incredibly hard to track down. is and ==? == checks if two values are equal. is checks if two variables point to the same object in memory. Here’s a simple way to remember it: 👉 == → “Do these things look the same?” 👉 is → “Are these things literally the same object?” A Quick Example a = [1, 2, 3] b = [1, 2, 3] print(a == b) # True: the contents are the same print(a is b) # False: different objects in memory Even though a and b contain the same list values, they’re not the same object.

Loops are a fundamental programming concept used to execute a block of code repeatedly under certain conditions. In JavaScript, loops are especially useful when working with arrays, objects, and repetitive tasks such as data processing or UI rendering. This article explores the different types of loops available in JavaScript, how to use them, and when each is most appropriate. Consider a scenario where you need to print numbers from 1 to 100. Without loops, you would have to write 100 console.log() statements. With loops, this task becomes simple and efficient: for (let i = 1; i <= 100; i++) { console.log(i); } Loops help reduce code redundancy, improve maintainability, and handle dynamic data structures efficiently. JavaScript provides several types of loops, each with its own syntax …  ( 5 min )

Whenever you need dynamic state that persists across re-renders, this is the one. const [count, setCount] = useState(0); Once your state becomes complex (e.g. multiple correlated fields), useReducer becomes your friend. It also pairs really well with useContext, letting you update state with simple dispatch calls. const reducer = (state, action) => { switch (action.type) { case "addTodo": return { todos: [...state.…  ( 6 min )

While I had built distributed software services before, this time was a different scenario altogether and, shall I say, much more interesting! This time was about building a payments processing service for two of the largest companies in the world to interact with one another, in a highly regulated environment. FTP was still involved, but at least the files were not in a fixed-width fields format! This time it was all about the CSV format, but that was not all: our Springboot application had to call existing Java remote services that were distributed across the globe. With that, came the first lesson: you can build vast distributed services on RPC technologies. The main advantage of REST is its HTTP/web interoperability. Because of that, REST APIs have a lot more traction in the western world where an entrepreneurial lattice of companies large and small thrive. But its lack of performance compared to RPC makes REST a less appealing option to large companies building large in-house systems that need to be fast and scalable in order to support their services offerings. Ant Financial uses its very own SOFA = Scalable Open Financial Architecture. SOFA allows for fast, low latency RPC calls at its core, also providing enterprise-ready capabilities such as fault tolerance, governance, observability and extensibility. https://github.com/sofastack  ( 3 min )

At work we recently moved. In the office we have automated blinds, these can be manually overwritten, so from my chair, they kind of live their own life. My solution is to switch appearance on macOS depending on the amount of light in the room. Most of the apps support switching between light and dark mode and follow the system settings. Many websites also do this and I even wrote the user story to get one of the products I manage to support this. A few applications however do need a little bit of help. So here I are a few I recently tweaked so they would still be usable in light mode - after all dark mode is the default, we all can agree on that. Do note I use macOS, but the material below should cover Windows as well - well untested from my side, but enough to get you going. Warp can fol…  ( 5 min )

When it comes to advancing in the tech world, many developers focus solely on hard skills—coding languages, frameworks, and technical certifications. While these are essential for getting a foot in the door, what truly elevates a developer from junior to senior level in 2025 is a refined set of non-technical skills. In an era dominated by managed IT services, automation, and agile development environments, the traditional role of the developer has expanded. Senior developers are expected to bridge the gap between technical solutions and business objectives. Effective Communication Collaboration and Teamwork Problem-Solving and Critical Thinking Technoholicas often relies on senior-level developers to make critical architecture decisions that align with client goals and long-term IT strategies.

Traditional security models based on "trust but verify" are no longer effective. In today’s perimeter-less IT world, Zero Trust is the new standard. It assumes that threats exist inside and outside the network. 🔒 Zero Trust principles: Never trust, always verify: Every user and device is authenticated continuously. Least privilege access: Give users only what they need—nothing more. Micro-segmentation: Reduce lateral movement by isolating critical systems. Real-time monitoring: Detect anomalies and respond instantly. Combining Zero Trust with robust endpoint protection, email security, and threat intelligence leads to a resilient cybersecurity posture.

If every new feature forces you to change what already works… something’s wrong.” Have you ever opened a service and added just one more if? At first, it feels harmless — just one more condition. This is exactly what the Open/Closed Principle (OCP) — the "O" in SOLID — helps you avoid. What is the OCP? In practice, it means you should be able to add new behavior without changing existing code. It’s not just about clean code. It’s about safety, scalability, and long-term maintenance. The less you change working code, the less you risk breaking it. The problem with “if-chains” public double CalculateFee(string paymentType) { Each new method requires changing the original method — and hoping you don’t break what’s already there. This clearly violates OCP — you’re modifying a core function instead of extending the system safely. Applying OCP in .NET public interface IPayment { public class Pix : IPayment { public class Boleto : IPayment { public class Card : IPayment { public class PaymentService { Want to add Apple Pay? That's the power of OCP — change through extension, not modification. Real benefits of applying OCP When not to apply OCP? Practical tip: Apply OCP when you expect varying behavior (payment types, notifications, report generation). Avoid overengineering in simple, stable domains. Final thoughts: OCP protects your code from the future The Open/Closed Principle gives your code a way to evolve without fear, keeping your foundation stable while adding value on top.  ( 4 min )

Existem dois tipos de operadores de incremento: o operador de pré-incremento (++variavel) e o operador de pós-incremento (variavel++). O operador de pré-incremento (++variavel) aumenta o valor da variável em 1 antes de usar a variável em uma expressão. Aqui está um exemplo: int num = 5; int resultado = ++num; //num é incrementado para 6 e depois atribuído a resultado System.out.println(num); // imprime 6 System.out.println(resultado); // imprime 6 Já o operador de pós-incremento (variavel++) aumenta o valor da variável em 1 depois de usar a variável em uma expressão.

Nessa fase, são definidos os requisitos de segurança, funcionais e não funcionais, como as regras que devem ser seguidas, incluindo normas como a LGPD. Além disso, as decisões tomadas aqui influenciam diretamente a arquitetura e o design do sistema, garantindo que a segurança seja considerada desde a estruturação inicial. Algumas perguntas importantes a serem respondidas incluem: Qual é a classificação dos dados de acordo com as políticas da empresa? Isso inclui dados pessoais e sensíveis, e deve ser especificado como cada tipo de dado será tratado. Quem terá acesso aos dados? Detalhar quem tem permissão para visualizar, alterar ou excluir os dados, com base nas políticas de controle de acesso. Políticas de Exclusão: Devemos definir e documentar políticas claras para a exclusão de dados, incluindo como e quando os dados devem ser removidos. Por exemplo, no nosso sistema, temos dados pessoais e acadêmicos das alunas. Quem terá permissão para ver esses dados? Quem pode alterá-los? Quais são as políticas de exclusão aplicadas? Na imagem, podemos ver que a aluna possui dados pessoais (nome, CPF, endereço, data de nascimento) e dados acadêmicos (notas, RA, frequência e histórico escolar). Nota Importante: Dados pessoais: são aqueles que permitem a identificação direta ou indireta de uma pessoa. Voltando ao exemplo, a aluna tem acesso apenas aos seus próprios dados(pessoais e acadêmicos), enquanto a professora tem acesso de visualização e também de edição apenas aos dados acadêmicos de suas alunas, podendo, por exemplo, alterar notas ou incluir justificativas para faltas. Já a administradora tem acesso a todos os dados pessoais, acadêmicos e administrativos de todos os usuários.  ( 4 min )

Para começarmos a entender o que é SSDLC (Secure Software Development Life Cycle), trouxe uma analogia para vocês. Eu sempre penso em como explicaria algo novo para a minha avó. Então, vamos à analogia e depois à explicação com exemplos. Análise de Requisitos (Planejamento): Nesta fase, você identifica os materiais e requisitos legais necessários para construir a casa, como consultar a prefeitura sobre regras e normas de construção. Arquitetura e Design: Você desenha a planta da casa, escolhendo materiais, planejando entradas e saídas, e definindo medidas de segurança, como alarme e fechaduras. Implementação: A casa começa a ser construída. Você percebe que, além do alarme, precisa adicionar câmeras para garantir mais segurança. Testes: Antes de entregar a casa, a equipe testa o funcionamento das instalações, como eletricidade, alarmes e janelas. Verifica se tudo está em ordem. Implantação: Antes de entregar a casa aos proprietários, engenheiros fazem uma análise para garantir que tudo foi construído corretamente. Se estiver tudo certo, a casa é entregue. Manutenção: A casa está funcionando, mas você precisa fazer manutenções regulares. O alarme ou câmeras podem precisar de atualizações ou trocas devido a falhas descobertas. Bom, agora vamos ao SSDLC :) Como vimos na analogia o SSDLC pode ser considerado uma construção de uma casa, com um Lego, onde cada fase do processo de desenvolvimento de software seguro é uma peça importante que, quando combinada com as outras, forma um software seguro. Ou seja, devemos pensar em segurança desde o início, já no planejamento, e não apenas a partir da codificação. A segurança deve estar presente em todas as fases do ciclo de desenvolvimento. Agora, vamos entender como funciona cada fase desse ciclo.  ( 3 min )

Pensando em segurança no desenvolvimento de software, onde geralmente a incluímos? Como pessoa desenvolvedora, posso pensar na fase de codificação, testes e implementação. Mas, se pensarmos um pouco antes, será que o início do desenvolvimento do software é na codificação? Não, sabemos que a codificação não é o começo. Então, por que não pensar e incluir segurança desde o início? SQL Injection teve sua primeira identificação em 1998. Fonte: https://phrack.org/issues/54/8.html Exemplo de report SQL Injection de julho de 2024. Fonte: https://hackerone.com/reports/2597543 Para responder a essas questões, vamos entender como funciona SSDLC (Secure Software Development Life Cycle) e como ele pode ser aplicado tanto em novos projetos quanto em softwares em desenvolvimento. No exemplo, temos uma página de login com os campos "username" e "password". Um agente mal-intencionado (a ameaça) deseja acessar o sistema para obter dados ou privilégios que ele não deveria ter. Ele pode tentar explorar brechas de segurança conhecidas. Quando ele encontra uma falha de segurança por exemplo no login (a vulnerabilidade), ele explora essa falha. Se o agente consegue acessar o sistema, o risco não é só o ato de acessar o sistema em si, mas sim a possibilidade de que a ameaça explore a vulnerabilidade e cause um impacto negativo, como roubo de dados, comprometimento do sistema, ou controle total, especialmente se ele conseguir fazer login como administrador. O risco acontece quando uma vulnerabilidade é explorada, e o impacto desse risco varia conforme o tipo de acesso obtido (por exemplo, um login de administrador representa um risco maior para a empresa). A vulnerabilidade é o ponto fraco que pode ser explorado por uma ameaça, resultando em risco de danos ao sistema.  ( 4 min )

After learning how to use sim800l module in my previous project, I decided to create a GPS tracker using the Arduino platform. This project combines a SIM800L module for communication and a Ublox Neo-6M GPS module for location tracking with help of satellites. Making this device is also easy as previous project, just instead of using led, i use a GPS module to get the location and a little changes in the sketch. I measured the current consumption of the device under load and its around 50mAh for sim800l module and 100mAh for gps module. In standby mode, it consumes around 20mAh.

I remember after I had completed all the Game Development lessons (especially Game Development 1 and 2) on CodeCombat, my final task was to create a minigame in Python and I was left with no comments or help of any kind on how to do that (apart from the lessons I had previously completed from the course). It always left me feeling so overwhelmed that I was unable to code anything, I would feel better the next day and then start coding my game. It should be no secret that learning to code is hard, but it is not helpful to keep thinking like that. It is much more beneficial to think of coding as a challenge as it changes your perception from coding is a struggle to coding is a challenge instead. Coding is a challenge like in a classic adventure game where the hero is going on quests, encounters problems along the way and sometimes has to face a huge and intimidating monster. Nobody knows everything, you learn as you go and coding is a challenge, a challenge you can always improve on! Do you ever feel stupid while learning to code?  ( 3 min )

Over the years, I’ve learned that a good API doesn’t start with code — it starts with thoughtful design. Design-First API is an approach where you define the API contract before writing any implementation code — typically using specifications like OpenAPI (Swagger). This lets teams agree on the shape and behavior of the API early in the development process. It’s especially powerful in microservice architectures, where clear, stable interfaces between services are critical. Clear separation of concerns Early alignment on requirements across frontend, backend, and cross-functional teams Automation: generate clients, server stubs, validation logic (tools like oapi-codegen help a lot) Living documentation that stays up-to-date with the actual implementation On previous projects — including a B2B wholesale platform and a document templating system — applying the Design-First approach helped us: Speed up development by enabling parallel workstreams Reduce integration bugs Keep service contracts clean and consistent Would you like me to share some practical examples from real-world implementations?

🌱 A Humble Beginning I still remember the very first time I wrote a program — it wasn’t some flashy game or AI model. It was a simple Python script to print the Fibonacci series. At that time, I didn’t even fully understand what recursion or iteration was. All I knew was that the sequence started with 0 and 1, and each new number was the sum of the previous two. That logic fascinated me. It felt like uncovering a hidden pattern in nature, and I was the one bringing it to life with code. a, b = 0, 1 for _ in range(10): print(a) a, b = b, a + b Simple. Elegant. Powerful. After writing that program, I became curious. I wanted to know why the Fibonacci numbers were so famous. That’s when I stumbled upon something amazing — the Golden Ratio, approximately 1.618, which appears not ju…  ( 4 min )

You’ve probably encountered situations where you need to write out a large number, and the longer it gets, the harder it is to tell how many digits it actually has. Is 130000000 equal to 13 million, 130 million, or 1.3 billion? At first glance, it’s a mess. $number = 130000000 // This number is 😐? One alternative is to use exponential notation, which makes the magnitude clear: $number = 130e6 // immediately obvious: 130 million 🤘 But for numbers like 133456115, writing it as 133.456115e6 starts to feel counterproductive. Starting with PHP 7.4, there’s a handy new syntax: the numeric literal separator. You can sprinkle underscores into your numbers to improve readability, just like you would in a miliseconds or any other long number that you want to ready clearly: $number = 130_000_000; // 🤩 WOW, that’s clearly 130 million! The underscores don’t change the value or the type: var_dump(130_000_000 === 130000000); // true (integer === integer) var_dump(130_000_000.000 === 130000000); // false (float !== integer) See the RFC for more details: PHP RFC PS: JavaScript supports a similar feature!  ( 3 min )

Hey folks 👋 Recently, I bought a Xiaomi RedmiBook 16 to get more mobility and separate my work environment. Everything was going great, until I booted into Linux and realized the Wi-Fi wasn’t working at all. After some digging, I found out the issue was related to the Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter. It turns out that after installing the OS or updating the kernel, the firmware breaks. Don’t ask me why, but several logs showed the adapter crashing on boot. If you’re facing the same issue, here’s a simple workaround that worked for me on Ubuntu. It should also help on other Debian-based distros like Kali, Mint, Deepin, Xubuntu and etc. When the kernel loads, the adapter crashes due to incompatible or missing firmware. You’ll likely see something like this in dmesg: ath10k_pci 0000:01:00.0: failed to fetch board data for bus=pci… ath10k_pci 0000:01:00.0: failed to load board file… To fix this, you need to manually replace the firmware files on your system. If you try searching online, you’ll find several tutorials recommending replacing the main firmware binary. The problem is, most of them point to the same source, and unfortunately, killernetworking.com has been offline for years. Luckily, I downloaded that binary back then and saved it to a personal drive, since this issue kept happening. I figured it might disappear one day... and it did. So I created a GitHub repository with a .deb package to make things easier. 1 - Clone this repository with this command: git clone https://github.com/rafael-hs/qualcomm-atheros-qca6174-firmware-adapter 2 - Enter the directory and install the .deb sudo apt install ./surface-go-wifi_0.0.5_amd64.deb 3 - Then reboot your system: sudo reboot That's it! After these steps, your Wi-Fi should be up and running. It worked perfectly on my Ubuntu install, and I’ve seen others confirm it on similar distros. If you run into any issues or have another solution, drop a comment. It might help someone else! Thanks for reading and good luck! 🚀  ( 4 min )

We’ve upgraded everything: medicine, space travel, warfare, communication. But education? Still stuck in the industrial age. Classrooms. Exams. Text-heavy content. One-size-fits-all lectures.

🤯Feeling Overwhelmed by AI? Everywhere you look, it’s: If you’re just starting out or midway into your coding journey like me, it’s easy to feel like you’re already behind. ✅ What AI is great at: Generating boilerplate code Suggesting syntax Explaining common errors Writing basic functions ❌What AI still sucks at: Understanding real users Solving open-ended problems Designing scalable systems Making smart trade-offs Making a creative work Example: AI can write a “To-Do List App” in seconds. But it won’t know if your users want reminders by email, SMS, or psychic vibes. Here’s how you beat AI: Play the human game. Think like a problem-solver: Ask better questions. Understand the "why" behind the feature. Design for people, not machines. Build with context: Example: AI made the image below using a simple prompt "give me image based on my blog topic" vs the the image generate with proper instruction (i.e. the cover image of this post) Seriously, don’t fight it—use it. Stuck on syntax? Ask AI. Need test cases? Let AI write the first draft. Confused by an error? Let it explain. But always double-check. AI makes stuff up sometimes (you prob already seen that). Want to stay ahead? Get really good at: Problem-solving Communication System design Product thinking These are things AI can’t fake. You don’t need to be faster than AI. You just need to be smarter, more thoughtful, and more human. Let AI do the boring stuff. You focus on building stuff that matters. Liked this post? Share it with a friend who’s stressed about AI.

To Cache or Not to Cache: Tradeoffs Between In-Memory Checks and Database Queries In software engineering, many real-world problems boil down to tradeoffs, and one recurring decision is whether to query the database multiple times or fetch once and operate on data in memory. This seemingly small architectural choice can shape performance, reliability, and maintainability in ways that are easy to overlook but matter deeply in production. One of the most fundamental and frequently encountered tradeoffs revolves around data access: when faced with needing multiple pieces of information about a single entity (like a user or an order), should we fetch everything once and perform checks in our application's memory, or should we make several targeted queries to the database, asking for specific…  ( 9 min )

Hello 👋 Back for a new MyUnisoft technical article, this time with the help of my colleague Nicolas MARTEAU. Today, we will share our journey to completely refactor our document management architecture and how we migrated from Nextcloud to Azure S3 as our storage technology. We weren’t able to cover every detail—both for security reasons 🛡️ and to protect sensitive data 🔒—but I hope you will enjoy what I could share. 😊 Until now, we have managed several tens of millions of documents with Nextcloud. However, stability and performance had become an issue, with regular downtime 🕒 and delays ⏳ of several minutes for a simple document upload at times. 💬 These upload delays sometimes led to misunderstandings among users. For example, in certain integrations, it was not uncommon for users t…  ( 9 min )

Quando pensamos em internacionalização (i18n) em projetos Rails, a abordagem mais comum é utilizar a API nativa do framework com chaves de tradução. No entanto, recentemente descobri uma alternativa que torna esse processo mais direto e com maior visibilidade do conteúdo traduzido: o uso do GetText. GetText é um framework utilizado no ecossistema Linux, que oferece um conjunto de ferramentas para facilitar a tradução de textos em aplicações. Integrado ao Rails, ele permite uma forma mais automática de localizar strings, sem a necessidade de criar e gerenciar nomes de chaves. No modelo tradicional com I18n, criamos chaves de tradução e mapeamos seus conteúdos em arquivos YML. Nas views, essas chaves são utilizadas da seguinte forma: t(".empty_state_message") # => Nenhum resultado encontrado…  ( 5 min )

I’ve spent the last few weeks organizing and refining my own incident response process for AWS. From handling Security Hub alerts to writing custom SES and Slack notifications, I needed more than just a checklist — I needed an actual toolkit. So I built one. ✅ A printable incident response checklist for triage ✅ An editable IR playbook aligned with ISO 27001 + AWS best practices ✅ Notification flows using EventBridge, SES, and Slack ✅ A cloud forensics tool matrix to guide acquisition and analysis ✅ Deployment-ready Terraform + Lambda code for alerting automation After publishing my free IR checklist on my blog, I realized many teams (and individuals) still struggle with: Rebuilding IR processes from scratch Responding to findings without a clear comms path Automating triage across teams or accounts I bundled everything I use — templates, scripts, docs — into one focused toolkit. When I started planning IR action plans this would have helped me a lot. You can explore the full breakdown + story behind it here: https://thehiddenport.dev/posts/aws-ir-toolkit/ And if you’re ready to grab it: Download the AWS IR Toolkit on Gumroad (€9) Includes all future updates, and a community where you can suggest changes. 💬 If you've built your own IR tools or want to share feedback — I'm all ears.

A new market catalyst is emerging from the intersection of political influence and crypto assets. The team behind the TRUMP memecoin has announced an exclusive gala dinner with former U.S. President Donald Trump, inviting the top 220 holders of the token. The top 25 will also receive a private tour of the White House. This event has generated increased interest in several related altcoins, particularly due to the potential visibility, speculative flows, and network effects surrounding the TRUMP ecosystem. The following three assets are positioned to benefit from this surge in attention. Technical Outlook: Bullish scenario: A breakout above the $0.267 resistance level could open the door to $0.279 as the next target. Bearish scenario: A failure to maintain support at $0.261 could lead to a…  ( 4 min )

Hey Dev.to friends! 👋 I’m just starting out with Python and honestly, every little step feels like a big victory. I’ve been working through some beginner problems, and while they might look simple to many, for me they’re a huge deal — and I wanted to share what I’ve learned so far. If you’re new to coding or struggling to get started, this is for you. Let’s celebrate the small wins together! Here’s what I tackled recently: Even or Odd Number Checker I learned how to use if-else conditions and handle errors gracefully when the user enters something unexpected. It was my first lesson in writing friendly code that doesn’t just break. Reverse a String Without Built-ins No shortcuts here! I figured out how to reverse a string by looping through each character — it really made me think like a programmer. Counting Vowels in a String This taught me how to loop through strings and do checks. Also, I learned that converting characters to lowercase makes checking easier, which was a neat trick. Celsius to Fahrenheit Converter I applied a real-world formula and added input validation — so the program politely asks for valid numbers instead of crashing. Word Count in a Sentence A simple but powerful way to split strings into words and count them, opening the door to more text processing challenges. Why This Matters Every expert was once a beginner. Small wins add up to big progress. Writing code is as much about mindset as it is about syntax. If you’re learning, don’t underestimate the power of these early steps. They build confidence and a solid foundation to tackle bigger challenges. What’s Next? Thanks for reading my story! 🙏 Happy coding! 💻✨  ( 4 min )

The command line got cool while you were stuck in the 2000s here’s how to level up Introduction Let’s be honest: if you’re still using the default terminal that came with your distro, it’s like showing up to a boss fight with a wooden sword. For a long time, the terminal was just… functional. You open it, run a few commands, maybe even SSH into something if you’re feeling fancy. But in 2025? That’s not enough. The modern dev stack has evolved and so have terminals. We’ve entered the age of GPU-accelerated rendering, autocomplete with AI, hyperconfigurable shells, and terminals that are so pretty they make your IDE jealous. Yet most of us are still stuck on gnome-terminal, xterm, or cmd.exe (gasp). It’s like driving a 1999 Corolla on a Formula 1 track. Respectable, but why? This article is …  ( 9 min )

Let’s be real: Ethereum is powerful, but it ain’t cheap. If you’ve ever written a Solidity contract and watched it burn gas faster than a Lamborghini in sport mode, this one’s for you. Whether you're minting NFTs, building DeFi protocols, gas optimization is the secret sauce to saving your users (and yourself) from unnecessary costs. Here are gas-saving tips every Ethereum developer should know in 2025 explained simply, with zero fluff. 1. Use uint256 by Default (and Consistently) uint8 or uint32 saves gas. Nope. uint256. It’s the native word size of the EVM and cheaper when used alone. // This is optimal: uint256 public totalSupply; // Not this: uint8 public totalSupply; // More expensive unless packed Rule: Go small only when you’re packing multiple variables into a single storage s…  ( 5 min )

Introduction Ever asked an AI to “make me a sandwich” and gotten a 500-word recipe for a virtual sandwich, complete with ASCII art of bread slices? Or prompted it to “write a love letter to my cat” and received a Shakespearean ode that’s both touching and slightly unhinged? If so, congratulations: your AI model thinks you’re weird. Don’t take it personally—it’s not judging you (well, not exactly). It’s just trying to make sense of the gloriously messy, unpredictable thing that is human intent. In 2025, AI models like me, Grok, or competitors such as GPT-4o and Claude are marvels of engineering, capable of generating text, code, and even creative stories with uncanny accuracy. But the relationship between what you mean and what the AI does is a strange dance of probability, context, and o…  ( 10 min )

A few years ago, detecting and responding to cyber threats meant signature-based systems, rule-heavy SIEMs, and a team of analysts swimming in alerts. Fast forward to today—and suddenly, it feels like cybersecurity is quietly undergoing a transformation right under our noses. What changed? We now have systems that can learn normal behavior, adapt to new threats in real time, and even simulate attack paths before they’re exploited. Not perfectly. Not universally. But undeniably. Whether you're deep in blue team operations or building dev tools, chances are you’ve already interacted with some layer of this new approach—whether you realized it or not. This isn’t just about automation. It’s about augmentation. Modern cyber defense strategies aren’t just faster—they’re smarter. But here’s the question that’s been stuck in my head lately: Are we trusting the machines too much, or not enough? Because while AI-based tools are making a real impact—from anomaly detection to adaptive access control—they’re also introducing new risks. Model poisoning. False positives at scale. A widening skills gap. And worst of all, a sense of overconfidence that the system will “catch it.” So where’s the balance? There's a free masterclass happening on 28th May that's diving into this exact space. It’s framed for IT leaders, but it looks like anyone interested in practical insights and forward-thinking strategies would benefit. I’ve already signed up, so if you’re exploring this frontier too, maybe we’ll cross paths there. 👉(https://www.netcomlearning.com/webinar/Cybersecurity-Masterclass-How-AI-is-Redefining-Cyber-Defense?utm_source=devto.com)  ( 3 min )

In Part 1, I wrote about how I transitioned from working with a team to building solo. Once I made that decision, I needed to start somewhere - and for me, that was authentication. This post covers how I approached it using FastAPI, why I avoided localStorage, and how I made authentication declarative with a custom router. There are many ways to handle authentication, but I chose the most popular and relatively reliable approach: JWT auth. The spec generally assumes two endpoints: One to get an access + refresh token One to get a new access token if the previous one has expired The client needs to store these tokens somewhere and send them with each request—usually in headers. They're often stored in localStorage, which isn’t very secure. But I wasn’t as concerned with security (this isn’…  ( 5 min )

Imagine someone says a word out loud: “eight” or “ate”. To a human ear, they sound almost identical, most people couldn’t tell them apart without context. So how does an AI system like Google Assistant or Siri know what the speaker meant? That’s where the beauty of speech recognition and natural language processing (NLP) kicks in. Let’s understand it down step by step: When you speak, your voice creates vibrations in the air. A microphone picks up those sound waves and converts them into digital data, essentially, a stream of numbers that represent how your voice changes over time. But AI doesn’t listen to this data the way humans do. Instead, it transforms it into a spectrogram, a visual map of sound over time. It’s like a heatmap that shows: Pitch (high or low sounds) Intensit…  ( 5 min )

With Redis, your Spring Boot app can become faster and handle more traffic without breaking a sweat. This article will show you how to set it up step by step. However, before diving deep into Redis, we need to understand the concept of caching. Cache Cache is a fast, small, temporary storage frequently used by the computer or application to store and access important data. It stores data in a key-value format. By leveraging cache memory, we can minimize database calls, improving application performance since database queries are typically resource-intensive. The main objective of a cache is to speed up the retrieval of data by making a copy of the data in a location that can be accessed faster than the source or database. A cache is a small and fast, efficient memory space that an appli…  ( 9 min )

About a month ago, I shared how my internship and final semester project came together perfectly, giving me the chance to dive into Laravel while building a platform to reduce food waste by connecting businesses with surplus food. I’m excited to say we’re nearly done! Over the past few weeks, our team has been polishing the app — fixing bugs, refining the user experience, and preparing for launch. The backend and database will be hosted soon, making the platform live and accessible. Looking Back at the Tech Stack: Backend: PHP Laravel — my internship experience gave me a strong foundation here, and I’ve deepened my understanding of scalable architecture, API development, and ORM relationships. Frontend: React — my teammate has built a clean, responsive UI that complements the functionality we’ve worked hard to develop on the backend, resulting in a seamless user experience across the platform. Database: MySQL — we designed the schema to handle complex relationships efficiently, especially for managing users, food listings, and organization profiles. This project has been both technically and personally rewarding. We’ve approached it like a real-world product, learning through every challenge. What’s Next: Deploying the backend and database online Final usability testing Gathering feedback for improvements If you’ve worked on something similar or have any tips for hosting and scaling Laravel apps, I’d love to connect and learn from your experience. Thanks for following along — more updates soon!  ( 3 min )

What breaking AI workflows taught me about the future of engineering. In traditional software development, when something breaks, you look at the logs. You dig into the stack trace, inspect variables, step through the debugger, isolate the bug. In AI-powered applications, that world is gone. When an LLM fails, there’s often no crash, no error, and no stack trace. Just a subtly wrong response. A hallucination. A weird behavior that’s technically correct but totally wrong for your user. Debugging becomes conversational. And that changes everything. In our product Linkeme, we rely on prompts to: Generate social media content Choose relevant CTAs Compose visual overlays And yet, some of the most frustrating bugs we faced early on didn’t come from bad code — but from poorly constructed prompts.…  ( 4 min )

Unlike traditional hardware firewalls that protect at the network edge, a software firewall is installed directly on host machines, virtual instances, or endpoints. Its primary job is to inspect, filter, and manage data traffic based on customized security rules. This digital guardian monitors both inbound and outbound connections, blocking suspicious activity and allowing only trusted communication to flow through.

The recipe first Avoid using ObjectId Type for Ambiguous Typing System Across Tiers by favoring Strings instead. This will result in simpler backend types and DTOs that are reusable at the front end without requiring any special tools. The main disadvantage of this approach is a slight decrease in performance, as strings are larger than ObjectIds and can impact fast sorting operations. This scenario originated from a real application. It seems we followed the basic rules in different steps but ultimately failed. It would be great if we had changed the architecture at the start. Our application has a stack consisting of NestJS, Angular, and Mongoose, all written in TypeScript. We successfully implemented reusing typings across tiers, but it appeared complicated. Each tier had its own typing system, which could have been optimized. A clue to the problem is that the type of the primary field _id is ObjectId, a complex type present only on the backend. This made it unnatural for it to be used on both the frontend and backend. Some tools were implemented to reuse these types on ObjectId. New UI types were created, which seemed to improve the application's typing system. However, the application became convoluted, and we didn't want to research the case of using plain string IDs because we thought our approach was correct and it worked everywhere except for MeteorJS projects. If we refused to use the ObjectId type, we could eliminate the need for these tools, new UI types, and even DTOs that work on both frontend and backend. To test this idea, we created a separate project where I implemented the concept. The only disadvantage is the potential impact on MongoDB performance, which I couldn't measure. Additionally, we experimented with meaningful primary IDs where demanded custom solutions where string type is demanded.  ( 3 min )

Hi, I'm the developer of JavaFactory — a code generation tool that automates Java development using LLMs. Most AI code tools I've tried (like Cursor, Copilot, etc.) produce general-purpose code that's often unusable in real-world projects. They might write code quickly, but the result is: unpredictable, hard to maintain, and often completely wrong ( not usable ). So I built something different: A tool where I can explicitly define patterns and precisely control which classes are referenced. Yes, it takes some upfront work to define the rules. But the result? → Code that's testable, maintainable, and consistent with your actual architecture. In this demo, 400 lines of Java code (including tests) were generated in 20 seconds. All tests passed without manual edits. If you're tired of copy-pasting boilerplate and want AI that respects your structure — give this a try. 🔗 GitHub: link JetBrains Marketplace  ( 3 min )

Introduction In TypeScript, you can define custom shapes using type aliases or interface. But when it comes to choosing between them, many developers ask: "TypeScript Type vs Interface?" The answer is increasingly clear: use type. While both share similarities, type offers more flexibility, supports complex patterns, and aligns better with modern TypeScript and frameworks. In this guide, you'll learn the differences, strengths, and why type is the better default. Both type and interface define object shapes or function signatures: // Using type type Point = { x: number; y: number }; type SetPoint = (x: number, y: number) => void; // Using interface interface Point { x: number; y: number } interface SetPoint { (x: number, y: number): void } They look and behave similarly here, but the d…  ( 5 min )

In the ever-evolving world of software development, a seismic shift is underway. Developers, once primarily focused on writing code and building applications, are increasingly stepping into a new role: that of AI workflow designers. This transformation is not driven by a deliberate career pivot but by the rapid integration of artificial intelligence (AI) tools into the development process. These tools are reshaping how software is built, tested, and deployed, turning developers into "accidental architects" who orchestrate complex AI-driven workflows rather than solely crafting lines of code. This blog explores this evolution, examining how AI tooling is redefining developer roles, the skills required to thrive in this new landscape, and the implications for the future of software developme…  ( 9 min )

You may remember how much did others tell you to write your tests first, see them fail, and only write your production code after that? It's one of the craziest waste of time in software development, but not for the reasons you may think. The #1 reason your teachers, mentors and your community forced you to write unit tests first was this: get testable code. So, have you just accepted the implied message that if you don't write your tests first, your code will be untestable? Does it feel like you always need to make an extra effort to turn your code testable but you're not exactly sure why? Turns out, long story short, what makes code untestable is side effects. A function that changes global state, or the state of other objects, listens to global events, reads global state or the state o…  ( 5 min )

What Is Rate Limiting & Why It Matters webdev api security scalability architecture Rate limiting is about controlling how often a client can hit your app or API. It helps prevent abuse, reduce server load, and ensure fair access for everyone. Without it, one bad actor (or even an accidental loop) can overload your system. Every time a client makes a request, your server tracks how many requests they’ve made within a defined time window. If they exceed that limit, the server denies further requests — usually with a 429 Too Many Requests response. Clients can make a certain number of requests per fixed time period (e.g. 100 per minute). Simple but can lead to burst traffic at the start of each window. Spreads the request limit more smoothly over time. Prevents sudden spikes that fixe…  ( 4 min )

A Technical Evaluation of Milvus and Chroma DB In the rapidly evolving AI infrastructure landscape, vector databases have emerged as critical components for handling high-dimensional data. This analysis examines two prominent contenders—Milvus and Chroma DB—through the lens of enterprise readiness and developer experience, providing actionable insights for technical teams. Architectural Philosophy & Deployment Performance Benchmarks Milvus achieves 15,000 QPS on 768D vectors with 8ms p95 latency (32-node cluster) Chroma DB manages 2,300 QPS at 28ms latency (standalone instance) The gap widens with complex operations: Milvus' proprietary ANNS algorithms outperform Chroma's FAISS-based implementation by 40% in recall accuracy at 1M+ scale. However, Chroma's memory-mapped indexes demonstrate advantages for frequent schema modifications during development cycles. Ecosystem Integration Native PyTorch/TensorFlow data loaders Automated versioning for vector snapshots Grafana/Prometheus monitoring templates Chroma prioritizes LLM workflows with: LangChain integration out-of-the-box OpenAI embedding API compatibility Dynamic metadata filtering optimized for RAG pipelines Enterprise Readiness Cost Considerations Technical Recommendation Both platforms continue evolving—Milvus recently added GPU-accelerated indexing, while Chroma introduced hybrid scalar-vector search in Q2 2024. Technical leaders should evaluate these systems through the prism of their operational maturity and scalability requirements rather than seeking a universal solution. Note: All benchmark data reflects testing on AWS c6i.8xlarge instances with 500M 512D vectors unless otherwise specified.  ( 4 min )

Today, I dived into the world of CSS transitions, and I was excited to see how a small piece of code can make a website feel more smooth and interactive. In this post, I’ll share what I learned and how transitions work in CSS. CSS transitions allow you to change property values smoothly (over a given duration) instead of instantly. For example, instead of a button changing color immediately when hovered, transitions let that color change happen gradually. Here’s the basic syntax of a CSS transition: selector { transition: property duration timing-function delay; } property: The CSS property you want to animate (e.g., background-color, width, transform) duration: How long the transition takes (e.g., 0.5s, 1s) timing-function (optional): The speed curve (e.g., ease, linear, ease-in, ease-out, ease-in-out) delay (optional): The delay before the transition starts Hover Me .btn { background-color: #4CAF50; color: white; padding: 10px 20px; border: none; transition: background-color 0.3s ease; } .btn:hover { background-color: #2E7D32; } When you hover over the button, the background color changes smoothly from green to dark green in 0.3 seconds. You can transition multiple properties like this: .box { width: 100px; height: 100px; background-color: red; transition: width 0.5s, background-color 0.3s; } .box:hover { width: 200px; background-color: blue; } Only animatable properties can be transitioned (e.g., color, background-color, transform, opacity, width, height, etc.) Use transition: all if you want all animatable properties to transition — but use it carefully, as it can affect performance. Combine transitions with pseudo-classes like :hover, :focus, or :active for better interactivity. Learning CSS transitions opened my eyes to how much they can improve the user experience of a website. They're simple to use but make a big impact visually. I’m excited to explore more about animations using @keyframes and the animation property next!  ( 4 min )

Is SaaS Really Dead? Several months ago, the internet was abuzz with the Microsoft CEO Satya Nadella saying, “SaaS is dead.” The conversation started with a question from Bill Gurley about whether Satya was worried that newer startups are building applications with an AI-first approach, which could obfuscate traditional infrastructure like Excel or CRM. Here is Satya’s response: I think, the notion that business applications exist, that's probably where they'll all collapse, right in the agent era because if you think about it, right, they are essentially CRUD databases with a bunch of business logic. The business logic is all going to these agents, and these agents are going to be multi repo CRUD Some people might assume he suggested that AI agents could or would replace SaaS. Howe…  ( 9 min )

In the world of data, change is the only constant. Over the last few decades, SQL (Structured Query Language) has reigned supreme as the go-to language for managing relational databases. Then came NoSQL, challenging the traditional norms with its flexibility and scalability. But today, a new player is emerging quietly yet powerfully: NewSQL. So, is SQL really dying? Is NoSQL losing its charm? And what exactly is NewSQL? Let’s break it down. The Era of SQL: A Quick Recap But as data exploded in volume, velocity, and variety — thanks to social media, IoT, and mobile apps — traditional SQL databases began to struggle with horizontal scalability and flexible schemas. The Rise and Struggles of NoSQL Schema-less design — ideal for unstructured or semi-structured data Lack of ACID guarantees The Death of SQL? The Silent Rise of NewSQL by Abhishek Shakya 🔑 Key Features of NewSQL Databases: Cloud-Native Architecture Real-Time Performance Data Integrity at Scale Simplified DevOps Real-World Use Cases Traditional SQL systems are struggling to keep up with modern demands. NoSQL tried to fill the gap but fell short in consistency and relational data handling. NewSQL is emerging as a modern solution, blending the best of both worlds: the familiarity of SQL and the power of NoSQL. The future isn’t SQL vs. NoSQL.

Software development commonly uses continuous integration (CI), continuous delivery (CD), Agile, and DevOps. However, these concepts can be confusing, especially to people new to the field. Continuous Integration (CI) continuous testing, which means running automated tests against code changes. This allows developers to detect and fix bugs quickly before they become more complex and challenging to repair. Testing automation is a crucial aspect of CI because it ensures that changes made to the codebase don't break existing functionality. Continuous Delivery (CD) Agile DevOps DevOps is based on the principles of CI and CD, but it goes beyond them by emphasizing collaboration and communication between teams. DevOps teams use various tools and practices, such as automated testing and continuou…  ( 6 min )

I am trying to create an application for Android TV using Kotlin. The goal is to launch the application automatically when the TV boots up. I have already created the app using a BootReceiver and BroadcastReceiver, which works correctly on Android 9 and below. However, it does not work on devices running Android 10 or above. I also created another version of the application as a launcher app. I disabled the system launcher through ADB and set my app as the default launcher. This also works perfectly on Android 9 and below, but not on Android 10 or above. How can I achieve the desired behavior on Android 10 and above?  ( 3 min )

This project is part one of a series of DevOps projects where I'm building a CI/CD pipeline! I'll be working on the next project in a few days to expand what I've learnt. I wanted to learn how to set up the foundation of a CI/CD pipeline. This project walked me through the process of launching an EC2 instance and using it to build and edit a web app — completely in the cloud. We started this project by launching an EC2 instance because EC2 instances are like virtual computers that live in the cloud. We want our web app to live entirely in the cloud, so we are launching an EC2 instance to even develop our web app's code. A key pair is a mechanism for us to access EC2 instances. I created a key pair that AWS stores the public part of, and I downloaded the private key. AWS will authenticate t…  ( 5 min )

In this article, we review lefthook.yml in n8n codebase. But what is lefthook? LeftHook is a fast and powerful Git hooks manager for any type of projects. npm install lefthook --save-dev Configure your hooks, install them once and forget about it: rely on the magic underneath. # Configure your hooks vim lefthook.yml # Install them to the git project lefthook install # Enjoy your work with git git add -A && git commit -m '...' I picked the installation and usage from the lefthook documentation. So obviously there is a lot of information in the documentation. We want to focus only on the options used in n8n lefthook.yml file. pre-commit: commands: biome_check: glob: 'packages/**/*.{js,ts,json}' run: pnpm biome check --write --no-errors-on-unmatched --files-ignore-unkn…  ( 4 min )
